Western blot - Anti-PAK4 antibody [EPR25195-73] (AB300503)

False colour image of Western blot : Anti-PAK4 antibody [EPR25195-73] (ab300503) staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red.

In Western blot, ab300503 was shown to bind specifically to PAK4. A band was observed at 68 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in PAK4 knockout cell line ab266807 (knockout cell lysate ab258560). To generate this image, wild-type and PAK4 knockout HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in Intercept^® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS 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.

The bands beneath the target band (68 kDa) are expected to be degradation products.
