    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: ROCK2 knockout HAP1 cell lysate (20 µg)
      Lane 3: HeLa cell lysate (20 µg)
      Lane 4: A10 cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab125025 observed at 165 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab125025 was shown to specifically react with ROCK2 when ROCK2 knockout samples were used. Wild-type and ROCK2 knockout samples were subjected to SDS-PAGE. ab125025 and ab8245 (loading control to GAPDH) were diluted 1/10 000 and 1/2000 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 h at room temperature before imaging.

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol and sodium azide (ab125025).

    • Immunocytochemistry/Immunofluorescence analysis of HeLa (human cervix adenocarcinoma) cells labelling ROCK2 with purified ab125025 at 1/250. Cells were fixed with 4% Paraformaldehyde and permeabilized with 0.1% Triton X-100. ab150077, Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. Cells were counter-stained with ab7291 anti-Tubulin (mouse mAb) primary and ab150120 (AlexaFluor®594 goat anti-mouse) secondary both at 1/1000 dilution. Nuclei were counterstained with DAPI (blue).

      For negative control 1, rabbit primary antibody and ab150120 (anti-mouse) secondary antibody were used. For negative control 2, ab7291 (mouse primary antibody) was used followed by ab150077 (anti-rabbit secondary antibody).

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab125025).
