Recombinant Anti-ROCK1 antibody [EPR638Y] (ab134181)

Lane 1: Wild type HAP1 whole cell lysate (40 µg)
Lane 2: ROCK1 knockout HAP1 whole cell lysate (40 µg)
Lane 3: HEK293 whole cell lysate (20 µg)
Lane 4: HeLa whole cell lysate (20 µg)

Lanes 1 - 4: Merged signal (red and green). Green - ab134181 observed at 165 kDa. Red - loading control, ab18058, observed at 130 kDa.

ab134181 was shown to specifically react with ROCK1 when ROCK1 knockout samples were used. Wild-type and ROCK1 knockout samples were subjected to SDS-PAGE. Ab134181 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 500 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.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma tissue sections labeling ROCK1 with Purified ab134181 at 1:1200 (1.28 µg/ml). Heat mediated antigen retrieval was performed using Bond™ Epitope Retrieval Solution 2 (pH 9.0). Tissue was counterstained with Hematoxylin. Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) secondary antibody was used at 1:0 dilution. PBS instead of the primary antibody was used as the negative control. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument.

Lanes 1- 2: Merged signal (red and green). Green - ab134181 observed at 160 kDa. Red - Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) observed at 50 kDa.

 ab134181 was shown to react with ROCK1 in wild-type HeLa cells in western blot. The band observed in CRISPR/Cas9 edited cell line ab264780 (CRISPR/Cas9 edited cell lysate ab257642) lane below 160kDa may represent truncated forms and cleaved fragments. This has not been investigated further. Wild-type HeLa and ROCK1 CRISPR/Cas9 edited HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab134181 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) were incubated overnight at 4°C at a 1 in 1000 dilution and a 1 in 20000 dilution respectively. 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 in 20000 dilution for 1 hour at room temperature before imaging.
