All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution
Predicted band size: 34 kDa
Observed band size: 18,22 kDa why is the actual band size different from the predicted?Caspase-7 is activated upon apoptotic induction. Caspase-7 p22 subunit (22 kDa) and p20 subunit (18 kDa) are observed. The molecular weight observed is consistent with what has been described in the literature (PMID: 16352606). This antibody reacts with an unidentifiable protein around 48 kDa. ab256469 was shown to specifically react with Caspase-7 in wild-type HAP1 cells as signal was lost in Caspase-7 knockout cells. Wild-type and Caspase-7 knockout samples were subjected to SDS-PAGE. ab256469 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™ instrument using the ECL technique. Blocking and Diluting Buffer and concentration: 5% NFDM/TBST.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab256469).

Cleaved Caspase-7 was immunoprecipitated from 0.35 mg HeLa (Human cervix adenocarcinoma epithelial cell) treated with 1µM Staurosporine for 3h whole cell lysate 10µg with ab256469 at 1/30 dilution (2µg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab256469. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used at 1/1000 dilution.
Lane 1: HeLa (Human cervix adenocarcinoma epithelial cell) treated with 1µM Staurosporine for 3h whole cell lysate 10µg
