Western blot - Anti-PAK2 antibody [EP796Y] - BSA and Azide free (AB227990)

False colour image of Western blot : Anti-PAK2 antibody [EP796Y] staining at 1/5000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab76293 was shown to bind specifically to PAK2. A band was observed at 65 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in PAK2 CRISPR-Cas9 edited cell line ab282648 (CRISPR-Cas9 edited cell lysate ab283047). The band observed in the CRISPR-Cas9 edited lysate lane below 65 kDa is likely to represent a truncated form of PAK2. This has not been investigated further and the functional properties of the gene product have not been determined. To generate this image, wild-type and PAK2 CRISPR-Cas9 edited HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % 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 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution. This data was developed using the same antibody clone in a different buffer formulation (ab76293).
