Figure 1. ChIP results obtained with the Diagenode antibody directed against H4K20me1
ChIP assays were performed using human osteosarcoma (U2OS) cells, the Diagenode antibody against H4K20me1 (cat. No. CS-034-100) and optimized PCR primer sets for qPCR. Chromatin was sheared with the Diagenode “Shearing ChIP” kit (cat. No. kch-redmod-100). ChIP was performed with the “OneDay ChIP” kit (cat. No. kch-oneDIP-060), using sheared chromatin from 1.6 million cells. A titration of the antibody consisting of 2, 5, 10 and 15 μl per ChIP experiment was analysed. IgG (5 μg/IP) was used as negative IP control. Quantitative PCR was performed with primers for the GAPDH promoter and for the coding region of the myogenic differentiation gene (MYOD), a gene that is inactive at normal conditions. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).
Figure 2. Determination of the titer
To determine the titer, an ELISA was performed using a serial dilution of the Diagenode antibody against H4K20me1 (cat. No. CS-034-100). The antigen used was a peptide containing the histone modification of interest. By plotting the absorbance against the antibody dilution (Figure 2), the titer of the antibody was estimated to be 1:8,000.
Figure 3. Cross reactivity test using the Diagenode antibody directed against H4K20me1
To check the specificity of the Diagenode antibody against H4K20me1 (cat. No. CS-034-050) a Dot Blot was performed with peptides containing other modifications of histone H4 or the unmodified sequence. Other histone modifications include mono- and dimethylation of the same lysine and acetylation of the nearby lysine 16. To determine the cross reactivity, 0.2 to 100 pmol of peptides were spotted on a membrane. Three different peptides for H4K16ac were used. The antibody was used at a dilution of 1:20,000. Figure 3 shows a high specificity of the antibody for the modification of interest.
Figure 4. Western blot analysis using the Diagenode antibody directed against H4K20me1
Histone extracts of HeLa cells (15 μg) were analysed by Western blot using the Diagenode antibody against H4K20me1 (cat. No. CS-034-100) diluted 1:750 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the right; the marker (in kDa) is shown on the left.

A <strong>nucleosome</strong> consists of one pair of each of the core histones (<strong>H2A</strong>, <strong>H2B</strong>, <strong>H3</strong> and <strong>H4</strong>) forming an octameric structure wrapped by 146 base pairs of DNA. The different nucleosomes are linked by the linker histone<strong> H1, </strong>allowing for further condensation of chromatin.</p> <p>The core histones have a globular structure with large unstructured N-terminal tails protruding from the nucleosome. They can undergo to multiple post-translational modifications (PTM), mainly at the N-terminal tails. These <strong>post-translational modifications </strong>include methylation, acetylation, phosphorylation, ubiquitinylation, citrullination, sumoylation, deamination and crotonylation. The most well characterized PTMs are <strong>methylation,</strong> <strong>acetylation and phosphorylation</strong>. Histone methylation occurs mainly on lysine (K) residues, which can be mono-, di- or tri-methylated, and on arginines (R), which can be mono-methylated and symmetrically or asymmetrically di-methylated. Histone acetylation occurs on lysines and histone phosphorylation mainly on serines (S), threonines (T) and tyrosines (Y).</p> <p>The PTMs of the different residues are involved in numerous processes such as DNA repair, DNA replication and chromosome condensation. They influence the chromatin organization and can be positively or negatively associated with gene expression. Trimethylation of H3K4, H3K36 and H3K79, and lysine acetylation generally result in an open chromatin configuration (figure below) and are therefore associated with <strong>euchromatin</strong> and gene activation. Trimethylation of H3K9, K3K27 and H4K20, on the other hand, is enriched in <strong>heterochromatin </strong>and associated with gene silencing. The combination of different histone modifications is called the "<strong>histone code</strong>”, analogous to the genetic code.</p> <p><img src="https://www.diagenode.com/img/categories/antibodies/histone-marks-illustration.png" /></p> <p>Diagenode is proud to offer a large range of antibodies against histones and histone modifications.

A <strong>nucleosome</strong> consists of one pair of each of the core histones (<strong>H2A</strong>, <strong>H2B</strong>, <strong>H3</strong> and <strong>H4</strong>) forming an octameric structure wrapped by 146 base pairs of DNA. The different nucleosomes are linked by the linker histone<strong> H1, </strong>allowing for further condensation of chromatin.</p> <p>The core histones have a globular structure with large unstructured N-terminal tails protruding from the nucleosome. They can undergo to multiple post-translational modifications (PTM), mainly at the N-terminal tails. These <strong>post-translational modifications </strong>include methylation, acetylation, phosphorylation, ubiquitinylation, citrullination, sumoylation, deamination and crotonylation. The most well characterized PTMs are <strong>methylation,</strong> <strong>acetylation and phosphorylation</strong>. Histone methylation occurs mainly on lysine (K) residues, which can be mono-, di- or tri-methylated, and on arginines (R), which can be mono-methylated and symmetrically or asymmetrically di-methylated. Histone acetylation occurs on lysines and histone phosphorylation mainly on serines (S), threonines (T) and tyrosines (Y).</p> <p>The PTMs of the different residues are involved in numerous processes such as DNA repair, DNA replication and chromosome condensation. They influence the chromatin organization and can be positively or negatively associated with gene expression. Trimethylation of H3K4, H3K36 and H3K79, and lysine acetylation generally result in an open chromatin configuration (figure below) and are therefore associated with <strong>euchromatin</strong> and gene activation. Trimethylation of H3K9, K3K27 and H4K20, on the other hand, is enriched in <strong>heterochromatin </strong>and associated with gene silencing. The combination of different histone modifications is called the "<strong>histone code</strong>”, analogous to the genetic code.</p> <p><img src="https://www.diagenode.com/img/categories/antibodies/histone-marks-illustration.png" /></p> <p>Diagenode is proud to offer a large range of antibodies against histones and histone modifications.

Although these enzymes have been implicated in control of replication origins, the specific contribution of H4K20 methylation to DNA replication remains unclear. Here, we show that H4K20 mutation in mammalian cells, unlike in <i>Drosophila</i>, partially impairs S-phase progression and protects from DNA re-replication induced by stabilization of PR-Set7. Using Epstein-Barr virus-derived episomes, we further demonstrate that conversion of H4K20me1 to higher H4K20me2/3 states by Suv4-20h is not sufficient to define an efficient origin <i>per se</i>, but rather serves as an enhancer for MCM2-7 helicase loading and replication activation at defined origins. Consistent with this, we find that Suv4-20h-mediated H4K20 tri-methylation (H4K20me3) is required to sustain the licensing and activity of a subset of ORCA/LRWD1-associated origins, which ensure proper replication timing of late-replicating heterochromatin domains.

A <strong>nucleosome</strong> consists of one pair of each of the core histones (<strong>H2A</strong>, <strong>H2B</strong>, <strong>H3</strong> and <strong>H4</strong>) forming an octameric structure wrapped by 146 base pairs of DNA. The different nucleosomes are linked by the linker histone<strong> H1, </strong>allowing for further condensation of chromatin.</p> <p>The core histones have a globular structure with large unstructured N-terminal tails protruding from the nucleosome. They can undergo to multiple post-translational modifications (PTM), mainly at the N-terminal tails. These <strong>post-translational modifications </strong>include methylation, acetylation, phosphorylation, ubiquitinylation, citrullination, sumoylation, deamination and crotonylation. The most well characterized PTMs are <strong>methylation,</strong> <strong>acetylation and phosphorylation</strong>. Histone methylation occurs mainly on lysine (K) residues, which can be mono-, di- or tri-methylated, and on arginines (R), which can be mono-methylated and symmetrically or asymmetrically di-methylated. Histone acetylation occurs on lysines and histone phosphorylation mainly on serines (S), threonines (T) and tyrosines (Y).</p> <p>The PTMs of the different residues are involved in numerous processes such as DNA repair, DNA replication and chromosome condensation. They influence the chromatin organization and can be positively or negatively associated with gene expression. Trimethylation of H3K4, H3K36 and H3K79, and lysine acetylation generally result in an open chromatin configuration (figure below) and are therefore associated with <strong>euchromatin</strong> and gene activation. Trimethylation of H3K9, K3K27 and H4K20, on the other hand, is enriched in <strong>heterochromatin </strong>and associated with gene silencing. The combination of different histone modifications is called the "<strong>histone code</strong>”, analogous to the genetic code.</p> <p><img src="https://www.diagenode.com/img/categories/antibodies/histone-marks-illustration.png" /></p> <p>Diagenode is proud to offer a large range of antibodies against histones and histone modifications.

A <strong>nucleosome</strong> consists of one pair of each of the core histones (<strong>H2A</strong>, <strong>H2B</strong>, <strong>H3</strong> and <strong>H4</strong>) forming an octameric structure wrapped by 146 base pairs of DNA. The different nucleosomes are linked by the linker histone<strong> H1, </strong>allowing for further condensation of chromatin.</p> <p>The core histones have a globular structure with large unstructured N-terminal tails protruding from the nucleosome. They can undergo to multiple post-translational modifications (PTM), mainly at the N-terminal tails. These <strong>post-translational modifications </strong>include methylation, acetylation, phosphorylation, ubiquitinylation, citrullination, sumoylation, deamination and crotonylation. The most well characterized PTMs are <strong>methylation,</strong> <strong>acetylation and phosphorylation</strong>. Histone methylation occurs mainly on lysine (K) residues, which can be mono-, di- or tri-methylated, and on arginines (R), which can be mono-methylated and symmetrically or asymmetrically di-methylated. Histone acetylation occurs on lysines and histone phosphorylation mainly on serines (S), threonines (T) and tyrosines (Y).</p> <p>The PTMs of the different residues are involved in numerous processes such as DNA repair, DNA replication and chromosome condensation. They influence the chromatin organization and can be positively or negatively associated with gene expression. Trimethylation of H3K4, H3K36 and H3K79, and lysine acetylation generally result in an open chromatin configuration (figure below) and are therefore associated with <strong>euchromatin</strong> and gene activation. Trimethylation of H3K9, K3K27 and H4K20, on the other hand, is enriched in <strong>heterochromatin </strong>and associated with gene silencing. The combination of different histone modifications is called the "<strong>histone code</strong>”, analogous to the genetic code.</p> <p><img src="https://www.diagenode.com/img/categories/antibodies/histone-marks-illustration.png" /></p> <p>Diagenode is proud to offer a large range of antibodies against histones and histone modifications.

Although these enzymes have been implicated in control of replication origins, the specific contribution of H4K20 methylation to DNA replication remains unclear. Here, we show that H4K20 mutation in mammalian cells, unlike in <i>Drosophila</i>, partially impairs S-phase progression and protects from DNA re-replication induced by stabilization of PR-Set7. Using Epstein-Barr virus-derived episomes, we further demonstrate that conversion of H4K20me1 to higher H4K20me2/3 states by Suv4-20h is not sufficient to define an efficient origin <i>per se</i>, but rather serves as an enhancer for MCM2-7 helicase loading and replication activation at defined origins. Consistent with this, we find that Suv4-20h-mediated H4K20 tri-methylation (H4K20me3) is required to sustain the licensing and activity of a subset of ORCA/LRWD1-associated origins, which ensure proper replication timing of late-replicating heterochromatin domains. Altogether, these results reveal Suv4-20h-mediated H4K20 tri-methylation as a critical determinant in the selection of active replication initiation sites in heterochromatin regions of mammalian genomes.</p>', 'date' => '2017-09-15', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/28778956', 'doi' => '', 'modified' => '2017-10-10 15:56:45', 'created' => '2017-10-10 15:56:45', 'ProductsPublication' => array( [maximum depth reached] ) ) ), 'Testimonial' => array(), 'Area' => array(), 'SafetySheet' => array() ) $country = 'US' $countries_allowed = array( (int) 0 => 'CA', (int) 1 => 'US', (int) 2 => 'IE', (int) 3 => 'GB', (int) 4 => 'DK', (int) 5 => 'NO', (int) 6 => 'SE', (int) 7 => 'FI', (int) 8 => 'NL', (int) 9 => 'BE', (int) 10 => 'LU', (int) 11 => 'FR', (int) 12 => 'DE', (int) 13 => 'CH', (int) 14 => 'AT', (int) 15 => 'ES', (int) 16 => 'IT', (int) 17 => 'PT' ) $outsource = false $other_formats = array() $edit = '' $testimonials = '' $featured_testimonials = '' $related_products = '' $rrbs_service = array( (int) 0 => (int) 1894, (int) 1 => (int) 1895 ) $chipseq_service = array( (int) 0 => (int) 2683, (int) 1 => (int) 1835, (int) 2 => (int) 1836, (int) 3 => (int) 2684, (int) 4 => (int) 1838, (int) 5 => (int) 1839, (int) 6 => (int) 1856 ) $labelize = object(Closure) { } $old_catalog_number = '<br/><small><span style="color:#CCC">(CS-034-100)</span></small>' $country_code = 'US' $img = 'banners/banner-cut_tag-chipmentation-500.jpg' $label = '<img src="/img/banners/banner-customizer-back.png" alt=""/>' $application = array( 'id' => '43', 'position' => '10', 'parent_id' => '40', 'name' => 'ChIP-qPCR (ab)', 'description' => '', 'in_footer' => false, 'in_menu' => false, 'online' => true, 'tabular' => true, 'slug' => 'chip-qpcr-antibodies', 'meta_keywords' => 'Chromatin Immunoprecipitation Sequencing,ChIP-Seq,ChIP-seq grade antibodies,DNA purification,qPCR,Shearing of chromatin', 'meta_description' => 'Diagenode offers a wide range of antibodies and technical support for ChIP-qPCR applications', 'meta_title' => 'ChIP Quantitative PCR Antibodies (ChIP-qPCR) | Diagenode', 'modified' => '2016-01-20 11:30:24', 'created' => '2015-10-20 11:45:36', 'ProductsApplication' => array( 'id' => '4213', 'product_id' => '2052', 'application_id' => '43' ) ) $slugs = array( (int) 0 => 'chip-qpcr-antibodies' ) $applications = array( 'id' => '43', 'position' => '10', 'parent_id' => '40', 'name' => 'ChIP-qPCR (ab)', 'description' => '', 'in_footer' => false, 'in_menu' => false, 'online' => true, 'tabular' => true, 'slug' => 'chip-qpcr-antibodies', 'meta_keywords' => 'Chromatin Immunoprecipitation Sequencing,ChIP-Seq,ChIP-seq grade antibodies,DNA purification,qPCR,Shearing of chromatin', 'meta_description' => 'Diagenode offers a wide range of antibodies and technical support for ChIP-qPCR applications', 'meta_title' => 'ChIP Quantitative PCR Antibodies (ChIP-qPCR) | Diagenode', 'modified' => '2016-01-20 11:30:24', 'created' => '2015-10-20 11:45:36', 'locale' => 'jpn' ) $description = '' $name = 'ChIP-qPCR (ab)' $document = array( 'id' => '548', 'name' => 'Datasheet H4K20me1 CS-034-100', 'description' => 'Datasheet description', 'image_id' => null, 'type' => 'Datasheet', 'url' => 'files/products/antibodies/Datasheet_H4K20me1_CS-034-100.pdf', 'slug' => 'datasheet-h4k20me1-cs-034-100', 'meta_keywords' => null, 'meta_description' => null, 'modified' => '2015-07-07 11:47:44', 'created' => '2015-07-07 11:47:44', 'ProductsDocument' => array( 'id' => '510', 'product_id' => '2052', 'document_id' => '548' ) ) $publication = array( 'id' => '3269', 'name' => 'Histone H4K20 tri-methylation at late-firing origins ensures timely heterochromatin replication', 'authors' => 'Brustel J. et al.', 'description' => '<p>Among other targets, the protein lysine methyltransferase PR-Set7 induces histone H4 lysine 20 monomethylation (H4K20me1), which is the substrate for further methylation by the Suv4-20h methyltransferase.
