Caspase-7, a 35kD cysteine protease, otherwise known as ICE-like Apoptotic Protease 3 (ICE-LAP3) is a member of the ICE/Ced-3 subfamily. Caspase-7 is an executioner caspase which undergoes proteolytic cleavage of its precursor to form active p12 and p20 subunits. Evidence that activation of Caspase-7 occurs during cell death induced by the cytokine death receptors
Fas/APO-1 and the receptor of tumor necrosis factor (TNFR-1), coupled with the fact that
granzyme-B activated Caspase-7 cleaves the nuclear enzyme poly (ADP-ribose) polymerase
(PARP), suggests an important role for Caspase-7 in both cytokine-mediated and Granzyme-B
mediated apoptosis pathways.
Applications:
Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested.
Recommended Dilution:
Western Blot: 1-2ug/ml
Immunohistochemistry (Paraffin): 2ug/ml; Does not require protein digestion pre-treatment of paraffin embedded sections e.g. trypsin or pronase prior to staining. Does not require antigen retrieval using heat treatment prior to staining.
Optimal dilutions to be determined by the researcher.
IHC Positive Control:
Skeletal Muscle Tissue
Storage and Stability:
