Recombinant Anti-PKC alpha antibody [Y124] (ab32376)

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: PKC alpha knockout HAP1 cell lysate (20 µg)
Lane 3: K562 cell lysate (20 µg)
Lane 4: HEK293 cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab32376 observed at 77 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab32376 was shown to specifically react with PKC alpha in wild-type HAP1 cells. No band was observed when PKC alpha knockout samples were examined. Wild-type and PKC alpha knockout samples were subjected to SDS-PAGE. ab32376 and ab8245 (loading control to GAPDH) were diluted 1/5000 and 1/1000 respectively and incubated overnight at 4°C. 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 1/10,000 dilution for 1 hour at room temperature before imaging.

Unpurified ab32376 staining PKCα in 200nM PMA-treated wild-type HAP1 cells (top panel) and PKCα in 200nM PMA-treated knockout HAP1 cells (bottom panel). The cells were treated with 200nM PMA for 30 minutes to induce translocation of PKCα to the cell membrane. The cells were then fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab32376 at 1/200 dilution and ab7291 at 1ug/ml concentration overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to Mouse IgG (Alexa Fluor® 594) (ab150117) at 2ug/ml (shown in pseudo-color red). Nuclear DNA was labelled in blue with DAPI.

This product also gave a positive signal under the same testing conditions in HAP1 cells fixed with 4% formaldehyde (10 min).

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

Unpurified ab32376 staining PKCα in wild-type HAP1 cells (top panel) and PKCα in knockout HAP1 cells (bottom panel). In untreated conditions, PKCα is expressed in the cytoplasm of the cells. The cells were then fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h.
