Western blot - Anti-Dnmt3a antibody [EPR18455-94] - BSA and Azide free (AB254009)

This data was developed using the same antibody clone in a different buffer formulation (ab227823).

Lanes 1-4 : Merged signal (red and green). Green - ab227823 observed at 125 kDa. Red - loading control ab8245 observed at 37 kDa.

ab227823 Anti-Dnmt3a antibody [EPR18455-94] was shown to specifically react with Dnmt3a in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab261793 (knockout cell lysate ab257128) was used. Wild-type and Dnmt3a knockout samples were subjected to SDS-PAGE. ab227823 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab227823)

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 ab227823, 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).

Blocking and dilution buffer : 5% NFDM/TBST.

ab227823 was shown to specifically react with wild-type HAP1 cells as signal was lost in Dnmt3a knockout cells. Wild-type and Dnmt3a knockout samples were subjected to SDS-PAGE. ab227823 and ab181602 (Rabbit anti-GAPDH loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/200,000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD® ChemiDoc™ MP instrument using the ECL technique.

The observed bands ranging from 75~125kDa represent different Dnmt3a isoforms.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab227823).
