 ab32087  Anti-MCL1 antibody [Y37]  was shown to specifically react with MCL1 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266838 (knockout cell lysate ab256986) was used.  Wild-type and MCL1 knockout samples were subjected to SDS-PAGE.  ab32087 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) 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.
