     ab134173 Anti-GSTK1 antibody [EPR1939] was shown to specifically react with GSTK1 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266112 (knockout cell lysate ab257461) was used.  Wild-type and GSTK1 knockout samples were subjected to SDS-PAGE.  ab134173 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated at room temperature for 2. 5 hours 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.
