Immunohistochemistry: Caspase-3 Antibody - (active/cleaved) [NB100-56113]

Immunohistochemistry: Caspase-3 Antibody - (active/cleaved) [NB100-56113]

Immunohistochemistry: Caspase-3 Antibody - (active/cleaved) [NB100-56113] - Immunohistochemistry analysis of sectioned tumor tissues from the MDA-MB-231 study. Each section was subjected to the specified antibody followed by a biotinylated secondary antibody. Detection was done using a DAB Peroxidase HRP Substrate Kit (brown) followed by Hematoxylin counterstaining (purple). Images were obtained using inverted bright field microscopy. Sectioning results are representative of three individual tumors. Scale bar is 50 microns. Statistical analysis using One-Way ANOVA. *p<0.05 vs tumor volume of the control.

Application Notes
Preferentially detects active caspase-3 (large subunit: ~14-21 kDa, and small subunit: ~10 kDa). However, it may also detect pro-caspase-3 (~32 kDa) in some cell or tissue systems. Nuclear immunostaining of caspase-3 is considered be an indication of active/cleaved caspase-3.

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).
