    Lanes 1-2: ab242127 Anti-FOXP4 antibody [EPR22714-2] was shown to react with FOXP4 in HepG2 cells in Western blot. Loss of signal was observed when FOXP4 knockout sample was used. Wild-type and FOXP4 knockout samples were subjected to SDS-PAGE. ab242127 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated at 4°C overnight at 1 in 1000 dilution and 1 in 10000 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 10000 dilution for 1 hour at room temperature before imaging.
