Intented use
This Caspase-3 antibodyis to be used only for research purposes and not for diagnostics..
Properties
If you buy Antibodies supplied by NJS poly they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
Immunogen
Amino acids 207-220 (RNSKDGSWFIQSLC-human) were used as the immunogen for this Caspase-3 antibody (100% mouse homology). This amino acid sequence is from the small subunit.
Notes
The stated application concentrations are suggested starting points. Titration of the Caspase-3 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
Species reactivity
Human (Homo sapiens), Mouse (Mus musculus), Rat ; Due to limited knowledge and inability to test the antibody against all known species, we cannot guarantee that no other cross reactivity can occur.
Additional description
Human and some mouse caspases are active in apoptosis and cell death and even in necrosis and inflammation. CASP Gene and orthologous enzymes have been identifies successfully in the signal transduction cascade and pathways.
Storage
After reconstitution, the Caspase-3 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20 deg. Celcius or lower. Cycles of freezing and thawing can denaturate the peptide chains of the antibodies and reduce their sensitivity and/or change their affinity. Prepare aliqotes in such a manner so that freeze-thaw cycles are minimized. Avoid repeated freezing and thawing.
Description
Cysteine-aspartic acid protease 3, also known as Apopain, CPP32, CPP32B, and YAMA, is a member of the cysteine-aspartic acid protease family. Western blot analysis of three cell lines revealed the prominent CASP3 band at 32 kD and 20 kD. Several human cancer cell lines showed coexpression of both variants at the mRNA and protein levels. Overexpression of the catalytically inactive Caspase-3 by human kidney cells offered some resistance to inducers of apoptosis, and CASP3 accumulation could be enhanced with addition of proteasome inhibitors. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Alternative splicing of this gene results in two transcript variants that encode the same protein. Orthologs have been identified in numerous mammals for which complete genome data are available. Unique orthologs are also present in birds, lizards, lissamphibians, and teleosts. Nicholson et al. developed a potent peptide aldehyde inhibitor and showed that it prevented apoptotic events in vitro, suggesting that the protein is important for the initiation of apoptotic cell death.
