|Application ||IHC-P, E|
|Other Accession||NP_004337, 14790119|
|Calculated MW||30 kDa|
|Application Notes||Caspase-3 antibody can be used for detection of Caspase-3 by immunohistochemistry at 5 µg/mL.|
|Other Names||Caspase-3 Antibody: CPP32, SCA-1, CPP32B, CPP32, Caspase-3, Apopain, CASP-3, caspase 3, apoptosis-related cysteine peptidase|
|Target/Specificity||CASP3; At least two isoforms of Caspase-3 are known to exist.|
|Reconstitution & Storage||Caspase-3 antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.|
|Precautions||Caspase-3 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Involved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-|-Gly-217' bond. Cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop- helix leucine zipper domain and the membrane attachment domain. Cleaves and activates caspase-6, -7 and -9. Involved in the cleavage of huntingtin. Triggers cell adhesion in sympathetic neurons through RET cleavage.|
|Tissue Location||Highly expressed in lung, spleen, heart, liver and kidney. Moderate levels in brain and skeletal muscle, and low in testis. Also found in many cell lines, highest expression in cells of the immune system|

Caspase-3 Antibody: Caspases are a family of cysteine proteases that can be divided into the apoptotic and inflammatory caspase subfamilies. Unlike the apoptotic caspases, members of the inflammatory subfamily are generally not involved in cell death but are associated with the immune response to microbial pathogens. The apoptotic subfamily can be further divided into initiator caspases, which are activated in response to death signals, and executioner caspases, which are activated by the initiator caspases and are responsible for cleavage of cellular substrates that ultimately lead to cell death. Caspase-3 is synthesized as an inactive proenzyme that undergoes proteolytic cleavage by caspases 8, 9 and 10 to produce 2 subunits, termed p20 and p11. These subunits dimerize to form the active enzyme. Caspase-3 proteolytically cleaves and activates other proteins such as caspases 6, 7 and 9.
