Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Rabbit Anti-Human Caspase-7 recognizes an epitope near the N-terminus of mouse, rat and human Caspase-7. This polyclonal antibody was purified using affinity chromatography.
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 pathogens1,2 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.3 Caspase-7 is an executioner caspase that was identified based on its homology with caspases 1 and 3, as well as the C. elegans cell death protein CED-3.4 Alternative splicing of Caspase-7 mRNA results in the production of 3 distinct isoforms.4 Caspase-7 activity can be directly inhibited by XIAP expression.5
