Western blot - Anti-Apolipoprotein E antibody [EP1374Y] - BSA and Azide free (AB271843)

ab52607 was shown to react with APOE in wild-type HAP1 cells in Western blot with loss of signal observed in a APOE knockout cell line. Wild-type HAP1 and APOE knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab52607 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with secondary antibodies at 0.2ug/mL before imaging.

Western blot - Anti-Apolipoprotein E antibody [EP1374Y] - BSA and Azide free (AB271843)

False colour image of Western blot : Anti-Apolipoprotein E antibody [EP1374Y] staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab52607 was shown to bind specifically to Apolipoprotein E. A band was observed at 34-37 kDa in wild-type HepG2 cell lysates with no signal observed at this size in APOE knockout cell line. To generate this image, wild-type and APOE knockout HepG2 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5 % milk in TBS-0.1 % Tween^® 20 (TBS-T) 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) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) at 1/20000 dilution.
