|WB||1/1000 - 1/10000. Detects a band of approximately 110 kDa (predicted molecular weight: 110 kDa).|
|ICC/IF||1/100 - 1/250.|
|IP||1/20 - 1/30.|
Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: PI 3 Kinase catalytic subunit alpha knockout HAP1 cell lysate (20 µg)
Lane 3: Jurkat cell lysate (20 µg)
Lane 4: MCF7 cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab40776 observed at 100,120 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab40776 was shown to recognize PI 3 Kinase catalytic subunit alpha when PI 3 Kinase catalytic subunit alpha knockout samples were used, along with additional cross-reactive bands. Wild-type and PI 3 Kinase catalytic subunit alpha knockout samples were subjected to SDS-PAGE. ab40776 and ab8245 (loading control to GAPDH) were diluted to 1/1000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
Immunocytochemistry/Immunofluorescence analysis of Jurkat cells labelling PI 3 Kinase catalytic subunit alpha with purified ab40776 at a dilution of 1/100. Cells were fixed with 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. ab150077, an Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. DAPI (blue) was used as the nuclear counterstain. ab7291, a mouse anti-tubulin (1/1000) and ab150120, an Alexa Fluor® 594-conjugated goat anti-mouse IgG (1/1000) were also used.
Control 1: primary antibody (1/100) and secondary antibody, ab150120, an Alexa Fluor® 594-conjugated goat anti-mouse IgG (1/1000).
ab40776 (purified) at a dilution of 1/20 immunoprecipitating PI 3 Kinase catalytic subunit alpha in Jurkat whole cell lysate.
Lane 1 (input): Jurkat whole cell lysate (10µg)
Lane 2 (+): ab40776 + Jurkat whole cell lysate.
Lane 3 (-): Rabbit monoclonal IgG (ab172730) instead of ab40776 in Jurkat whole cell lysate.
For western blotting, ab131366 VeriBlot for IP (HRP) was used as the secondary antibody (1/1000).
