Background: Caspase-3

CPP32 encodes a member of the cysteine-aspartic acid protease (caspase) family that plays a key role in apoptosis. Caspase 3 (also known as CPP32, Apopain, Yama, and PARP cleavage protease) is the most extensively studied apoptotic protein among caspase family members (1-2). Caspase 3 is synthesized as an inactive proenzyme that is processed in cells undergoing apoptosis by self-proteolysis and/or cleavage by other upstream proteases (e.g. Caspases 8, 9 and 10). Alternative splicing of CPP32 results in two transcript variants which encode the same protein. The processed form of Caspase 3 consists of large (theoretical molecular weight 17kD) and small (theoretical molecular weight 12kD) subunits which associate to form an active enzyme. Caspase 3 is cleaved at Asp28/Ser29 and Asp175/Ser176. The active Caspase 3 proteolytically cleaves and activates other caspases (e.g. Caspases 6, 7 and 9), as well as relevant targets in the cells (e.g. PARP and DFF). Variations in levels of Caspase 3 have been reported in cells of short-lived nature and those with a longer life cycle. Caspase 3 is the predominant caspase involved in the cleavage of amyloid beta 4A precursor protein, which is associated with neuronal death in Alzheimer's disease (3).

FAQs for Caspase-3 Antibody

Showing  1 - 4 of 4 FAQs Showing All

  • Q: Any reason for cleaved caspase 3 to be seen as purely nuclear staining or is this just an artifact?

    A: Caspase-3 can translocate from the cytoplasm to the nucleus, usually during apoptosis. We do offer a 100% guarantee that this antibody will be useful as stated on the datasheet also.

  • Q: I'd like to get the information about the active/cleaved Caspase-3 (NB600-1235). The datasheet says that it reacts with the active form of Caspase-3 (17 kDa protein), but every time when I do the WB, I get two bands between 15kDa and 20kDa. The different company's cleaved caspase 3 antibody reacts with 17 and 19 kDa protein, so I wonder which band is specific to yours? 

    A: According to the data I could find for the active/cleaved caspase 3, the active form should appear at approximately 17kDa and also has a smaller subunit seen at approximately 12kDa. The inactive form is approximately 32kDa. These are the theoretical weights and can vary based on type of gel and samples they are run on. In most cases, it looks like most antibodies detect the active forms at 19 and 17kDa respectively. With this particular product, NB600-1235, we have not yet validated it for use in western blot, so we unfortunately do not have any information for the location of bands.

    A: Regarding your question, NB600-1235 has been exclusively validated for IHC, not western blot and it is supposed to detect the active form of caspase3. The inactive Caspase 3 is a 31 kD protein, a heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 17 kDa (p17) and a 12 kDa (p12). When it is Cleaved by granzyme B, it generates the two active subunits. As a result the two bands you are observing on the gel should be correct. However, we haven't tested this antibody for western blot.

  • Q: This is a Rabbit antibody right so Do you think I can use it on rabbit tissue?

    A: This antibody does react to rabbit but if you are using it with an anti-rabbit secondary, you will almost certainly see some background staining. I know that mouse-on-mouse blocking systems exist, but I am not sure if there is a rabbit equivalent at this time. The best way to use NB600-1235 on rabbit tissues would be to have it directly conjugated to biotin, HRP, or whatever detection method you are planning to use. This will eliminate the need for an anti-rabbit secondary and should give you little to no background. We do offer a custom conjugation service, so if you would like to have this antibody conjugated, please send an email to let me know what you would like to have this antibody conjugated to and I can get you a quote.
