ab40776 staining PI 3 Kinase catalytic subunit alpha in the human cell line Jurkat (human acute T cell leukemia) by flow cytometry. Cells were fixed with 4% paraformaldehyde, permiabilised with 90% methanol and the sample was incubated with the primary antibody at a dilution of 1/40. A goat anti rabbit IgG (Alexa Fluor® 488) at a dilution of 1/2000 was used as the secondary antibody.
Isoytype control: Rabbit monoclonal IgG (Black)
Unlabelled control: Cell without incubation with primary antibody and secondary antibody (Blue)
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 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 (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
Lanes 1 - 3: Merged signal (red and green). Green - ab40776 observed at 124 kDa. Red - loading control, ab8245, observed at 37 kDa.
This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab40776 and ab8245 (loading control) overnight at 4°C. Antibody binding was detected using Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at a 1:10000 dilution for 1hr at room temperature and then imaged.
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.
