Our Abpromise guarantee covers the use of ab32021 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/500. Detects a band of approximately 50 kDa (predicted molecular weight: 49 kDa).
Detects bands of approximately 50 kDa (pro form) and 18 kDa (p18 cleaved form).
FunctionInvolved in the activation cascade of caspases responsible for apoptosis execution. Might function by either activating some proteins required for cell death or inactivating proteins necessary for cell survival.
Tissue specificityExpressed at higher levels in the embryonic lung, liver and kidney than in the heart and brain. In adults, higher level expression is seen in the placenta, lung, kidney, and pancreas than in the heart, brain, liver and skeletal muscle.
Sequence similaritiesBelongs to the peptidase C14A family.
Contains 1 CARD domain.
modificationsThe mature protease can process its own propeptide, but not that of other caspases.

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: Caspase 2 knockout HAP1 cell lysate (20 µg)
Lanes 1 and 2: Merged signal (red and green). Green - ab182738 observed at 51 kDa. Red - loading control, ab8226, observed at 42 kDa.
ab32021 was shown to recognize caspase 2 when caspase 2 knockout samples were used, along with additional cross-reactive bands. Wild-type and caspase 2 knockout samples were subjected to SDS-PAGE. ab32021 and ab8226 (loading control to beta actin) were diluted 1/50 and 1/1000 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 1/10000 dilution for 1 h at room temperature before imaging.
Anti-Caspase-2 antibody [Y154] (ab32021) at 1/500 dilution + Jurkat cell lysate.
Predicted band size: 49 kDa
Observed band size: 50 kDa why is the actual band size different from the predicted?
Additional bands at: 18 kDa (possible cleavage fragment)
