Lane 1: Wild type HAP1 whole cell lysate (20 µg)
Lane 2: STAT1 alpha knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa whole cell lysate (20 µg)
Lane 4: A431 whole cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab109320 observed at 90 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab109320 was shown to recognize STAT1 alpha when STAT1 alpha knockout samples were used, along with additional cross-reactive bands. Wild-type and STAT1 alpha knockout samples were subjected to SDS-PAGE. Ab109320 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/10000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized MCF-7(Human breast adenocarcinoma cell line) cell line labeling STAT1 with ab109320 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green).
