    This data was developed using the same antibody clone in a different buffer formulation (ab229192).

    Lanes 1-4: Merged signal (red and green). Green - ab229192 observed at 53 kDa. Red - loading control ab8245 observed at 37 kDa.

     ab229192 Anti-Cdk8 antibody [EPR21005] was shown to specifically react with Cdk8 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265087 (knockout cell lysate ab257885) was used. Wild-type and Cdk8 knockout samples were subjected to SDS-PAGE. ab229192 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 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.

    Cdk8 was immunoprecipitated from 0.35 mg of SW480 (human colorectal adenocarcinoma cell line) whole cell lysate with ab229192 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab229192 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used for detection at 1/10,000 dilution.

    Lane 1: SW480 whole cell lysate 10 μg (Input).
    Lane 2: ab229192 IP in SW480 whole cell lysate.
    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab229192 in SW480 whole cell lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 3 minutes.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab229192).

    ab229192 was shown to specifically react with Cdk8 in wild-type HAP1 cells as signal was lost in Cdk8 knockout cells.

    Wild-type and Cdk8 knockout samples were subjected to SDS-PAGE. ab229192 and ab181602 (Rabbit anti-GAPDH loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/200,000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD® ChemiDoc™ MP instrument using the ECL technique.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab229192).
