m66A Antibody (sample size)

Figure 1. RNA immunoprecipitation using the Diagenode antibody directed against m66A
RNA immunoprecipitation (RIP) was performed on 40 µg total RNA isolated from HeLa cells using 2 µg of the Diagenode antibody against m66A (cat. No. C15410365) or with an equal amount of mouse IgG, used as a negative control. The immunoprecipitated RNA was subsequently analysed on a Bioanalyzer. Figure 1A shows the Bioanalyzer profile obtained with the m66A antibody (left) The right panel shows the input. Figure 1B shows the gel image for the m66A antibody, the IgG negative control and the input (lane 1, 2 and 3, respectively). The marker (in bp) is shown on the left, the position of the 28s and 18s ribosomal RNA is indicated on the right.

Figure 2. RNA immunoprecipitation using the Diagenode antibody directed against m66A
RIP assays were performed on 40 µg total RNA from human HeLa cells using the Diagenode m66A antibody (cat. nr. C15410365). A titration of the antibody consisting of 1, 2 and 5 µg per RIP experiment was analysed. IgG (2 µg/IP) was used as negative IP control. QRT-PCR was performed with primers for the 18s and 28s rRNA genes. Figure 2 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).

Figure 3. Dot blot analysis using the Diagenode antibody directed against m66A
To demonstrate the specificity of the Diagenode antibody against m66A (cat. No. C15410365), a Dot Blot analysis was performed using in vitro transcribed RNA molecules containing m6A or m66A modified bases as well as an unmodified control RNA. 5 and 2.5 ng of the respective RNA molecules were spotted on the membrane. The antibody was diluted of 1:400 in TBS-T containing 10 % skimmed milk and 1% BSA. Figure 1 shows a high specificity of the antibody for the oligonucleotide with the N6N6-dimethyladenosine.
