'description' => 'CRISPR systems are adaptable immune mechanisms which are present in many bacteria to protect themselves from foreign nucleic acids, such as viruses, transposable elements or plasmids. The CRISPR/Cas9 (CRISPR-associated protein 9 nuclease) system from S. pyogenes was the first to be adapted for inducing sequence-specific double stranded breaks and targeted genome editing. This system is unique and flexible due to its dependence on RNA as the moiety that targets the nuclease to a desired DNA sequence and can be used to induce indel mutations, specific sequence replacements or insertions and large deletions or genomic rearrangements at any desired location in the genome. In addition, Cas9 can also be used to mediate upregulation of specific endogenous genes or to alter histone modifications or DNA methylation. Recently, a so-called class 2 type VI CRISPR system has been identified which is characterized by the presence of the single effector protein. Cas13a is one of the proteins belonging to the class 2 type VI system identified so far. These proteins lack homology to other DNA nuclease domains but contain two Higher Eukaryotes and Prokaryotes Nucleotide-binding (HEPN) domains and are thought to function solely as an RNA-guided RNA-targeting CRISPR effector.',

<h3><a name="4reasons"></a>Four critical reasons to use anti-CRISPR/Cas9 antibodies</h3>
<p>CRISPR/Cas9 genome editing allows for double-stranded DNA breaks at specific sequences to efficiently disrupt, excise, mutate, insert, or replace genes. The precision of transfection and the level of Cas9 expression should be controlled during the editing processes using specific anti-CRISPR/Cas9 antibodies.</p>

<h4><strong>Reason #3</strong> Check the Cas9 expression level</h4>
<p><strong>Transient systems</strong>: Check that <strong>Cas9 expression</strong> was transient by using <strong>Western blot</strong> and anti-Cas9 antibodies. Prolonged Cas9 expression will lead to more off-target mutations.</p>
<p><strong>Stable transformants</strong>: Isolate several clones and screen to check the level of <strong>Cas9 expression</strong> using <strong>Western blot</strong> and specific anti-Cas9 antibodies. High level of Cas9 expression can lead to non-specific activity.</p>

<h4><strong>Reason #4</strong> Check the binding specificity of Cas9</h4>

<h3><a name="4reasons"></a>Four critical reasons to use anti-CRISPR/Cas9 antibodies</h3>
<p>CRISPR/Cas9 genome editing allows for double-stranded DNA breaks at specific sequences to efficiently disrupt, excise, mutate, insert, or replace genes. The precision of transfection and the level of Cas9 expression should be controlled during the editing processes using specific anti-CRISPR/Cas9 antibodies.</p>

<div class="small-10 medium-10 large-10 columns">
<h4><strong>Reason #1</strong> Check the transfection success of the Cas9 protein</h4>
<p>Check <strong>Cas9 expression level</strong> using <strong>Western blot</strong> with validated anti-Cas9 antibodies.</p>

<div class="small-10 medium-10 large-10 columns">
<h4><strong>Reason #3</strong> Check the Cas9 expression level</h4>
<p><strong>Transient systems</strong>: Check that <strong>Cas9 expression</strong> was transient by using <strong>Western blot</strong> and anti-Cas9 antibodies. Prolonged Cas9 expression will lead to more off-target mutations.</p>
<p><strong>Stable transformants</strong>: Isolate several clones and screen to check the level of <strong>Cas9 expression</strong> using <strong>Western blot</strong> and specific anti-Cas9 antibodies. High level of Cas9 expression can lead to non-specific activity.</p>

<h4><strong>Reason #4</strong> Check the binding specificity of Cas9</h4>
<p>Test the binding specificity with an sgRNA of choice by using the <strong>ChIP-grade anti-Cas9 antibody</strong> and the primers for targeted and non-targeted region to see if Cas9 is bound to the correct region.</p>

<h3><a name="4reasons"></a>Four critical reasons to use anti-CRISPR/Cas9 antibodies</h3>
<p>CRISPR/Cas9 genome editing allows for double-stranded DNA breaks at specific sequences to efficiently disrupt, excise, mutate, insert, or replace genes. The precision of transfection and the level of Cas9 expression should be controlled during the editing processes using specific anti-CRISPR/Cas9 antibodies.</p>

<div class="small-10 medium-10 large-10 columns">
<h4><strong>Reason #1</strong> Check the transfection success of the Cas9 protein</h4>

<h4><strong>Reason #3</strong> Check the Cas9 expression level</h4>
<p><strong>Transient systems</strong>: Check that <strong>Cas9 expression</strong> was transient by using <strong>Western blot</strong> and anti-Cas9 antibodies. Prolonged Cas9 expression will lead to more off-target mutations.</p>
<p><strong>Stable transformants</strong>: Isolate several clones and screen to check the level of <strong>Cas9 expression</strong> using <strong>Western blot</strong> and specific anti-Cas9 antibodies. High level of Cas9 expression can lead to non-specific activity.</p>

<h4><strong>Reason #4</strong> Check the binding specificity of Cas9</h4>
<p>Test the binding specificity with an sgRNA of choice by using the <strong>ChIP-grade anti-Cas9 antibody</strong> and the primers for targeted and non-targeted region to see if Cas9 is bound to the correct region.</p>

The CRISPR/Cas9 (CRISPRassociated protein 9 nuclease) system from S. pyogenes was the first to be adapted for inducing sequencespecific double stranded breaks and targeted genome editing. This system is unique and flexible due to its dependence on RNA as the moiety that targets the nuclease to a desired DNA sequence and can be used to induce indel mutations, specific sequence replacements or insertions and large deletions or genomic rearrangements at any desired location in the genome. In addition, Cas9 can also be used to mediate upregulation of specific endogenous genes or to alter histone modifications or DNA methylation. Recently, a socalled class 2 type VI CRISPR system has been identified which is characterized by the presence of the single effector protein. Cas13a is one of the proteins belonging to the class 2 type VI system identified so far. These proteins lack homology to other DNA nuclease domains but contain two Higher Eukaryotes and Prokaryotes Nucleotide-binding (HEPN) domains and are thought to function solely as an RNA-guided RNA-targeting CRISPR effector.</p>',

The best characterized CRISPR-associated nucleases are the <strong>Cas9 proteins</strong> from <em>Streptococcus pyogenes</em> and <em>Staphylococcus aureus</em>.

<h3><a name="4reasons"></a>Four critical reasons to use anti-CRISPR/Cas9 antibodies</h3>
<p>CRISPR/Cas9 genome editing allows for double-stranded DNA breaks at specific sequences to efficiently disrupt, excise, mutate, insert, or replace genes. The precision of transfection and the level of Cas9 expression should be controlled during the editing processes using specific anti-CRISPR/Cas9 antibodies.</p>

<div class="small-2 medium-2 large-2 columns"><img src="https://www.diagenode.com/img/product/antibodies/cas9-reason-1.png" /></div>
<div class="small-10 medium-10 large-10 columns">
<h4><strong>Reason #1</strong> Check the transfection success of the Cas9 protein</h4>
<p>Check <strong>Cas9 expression level</strong> using <strong>Western blot</strong> with validated anti-Cas9 antibodies.</p>

<div class="small-10 medium-10 large-10 columns">
<h4><strong>Reason #2</strong> Check that the Cas9 protein was delivered to the nucleus</h4>
<p>Determine the nuclear localization of Cas9 protein via <strong>IF</strong> or <strong>IHC</strong> using validated anti-Cas9 antibodies</p>

<div class="small-10 medium-10 large-10 columns">
<h4><strong>Reason #3</strong> Check the Cas9 expression level</h4>
<p><strong>Transient systems</strong>: Check that <strong>Cas9 expression</strong> was transient by using <strong>Western blot</strong> and anti-Cas9 antibodies. Prolonged Cas9 expression will lead to more off-target mutations.</p>
<p><strong>Stable transformants</strong>: Isolate several clones and screen to check the level of <strong>Cas9 expression</strong> using <strong>Western blot</strong> and specific anti-Cas9 antibodies. High level of Cas9 expression can lead to non-specific activity.</p>

<div class="small-10 medium-10 large-10 columns">
<h4><strong>Reason #4</strong> Check the binding specificity of Cas9</h4>
<p>Test the binding specificity with an sgRNA of choice by using the <strong>ChIP-grade anti-Cas9 antibody</strong> and the primers for targeted and non-targeted region to see if Cas9 is bound to the correct region.</p>
