N6-methyladenosine (m6A) polyclonal antibody

Figure 1. RNA immunoprecipitation using the Diagenode antibody directed against m6A
RNA Immunoprecipitation was performed on 40 µg HeLa total RNA spiked with 0.5 µg of an in vitro prepared transcript containing m6A nucleotides, using 2 µg of the Diagenode m6A antibody (Cat. No. C15410208). An equal amount of IgG was used as negative control. The immunoprecipitated RNA was subsequently analyzed by qRT-PCR with primers specific for the transcript and for an intergenic region, used as negative control. 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. Dot blot analysis using the Diagenode antibody directed against m6A
To demonstrate the specificity of the Diagenode antibody against m6A (Cat. No. C15410208), a Dot Blot analysis was performed using synthetic oligonucleotides containing different modified bases. 150 and 50 pmol of the respective oligo’s were spotted on the membrane. The antibody was diluted 1:400 in PBS-T containing 10 % skimmed milk and 1% BSA. Figure 1 shows a high specificity of the antibody for the oligonucleotide with the N6-methyladenosine modification.
