Western blot - Anti-Dnmt3a antibody [EPR26805-273] (AB307503)

Blocking and diluting buffer and concentration : Intercept^® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS. The samples were run on a Bis-Tris gel.

False colour image of Western blot : Anti-Dnmt3a antibody ab307503 staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody 6C5 loading control staining at 1/20000 dilution, shown in red. In Western blot, ab307503 was shown to bind specifically to Dnmt3a. A band was observed at 125 kDa in wild-type Hela cell lysates whereas no signal observed at this size in Dnmt3a knockout cell line (ab261793). To generate this image, wild-type and Dnmt3a knockout Hela cell lysates were analyzed. First, samples were run on a SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in in Intercept^® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) at 1/10000 dilution and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

ChIC/CUT&RUN sequencing - Anti-Dnmt3a antibody [EPR26805-273] (AB307503)

CUT&RUN profiling with Dnmt3a antibody reveals the expected genomic enrichment pattern in cells. Representative genome browser tracks show CUT&RUN data generated using the CUTANA™ CUT&RUN Kit (EpiCypher 14-1048) with Dnmt3a antibody (Abcam ab307503, 0.5 µg). 500,000 HeLa cells were used per reaction. IgG, H3K4me3, and H3K27me3 antibodies were included as controls to assess non-specific background, active promoters, and repressed chromatin, respectively. Libraries were prepared using the CUTANA™ CUT&RUN Library Prep Kit (EpiCypher 14-1001). Sequencing was performed with paired-end 50 bp reads, and data were processed on CUTANA™ Cloud (cloud.epicypher.com) by alignment to the hg38 genome. Images were generated using Integrative Genomics Viewer (IGV, Broad Institute).
