Protocol
Specificity / Sensitivity
Perforin (E3W4I) Rabbit mAb recognizes endogenous levels of total perforin protein. High expressing cells like CTLL-2 can produce several low molecular weight bands due to degradation of the protein. Non-specific staining was observed in mouse salivary gland by immunohistochemistry.
Species Reactivity:
Mouse
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gln63 of mouse perforin protein.
Background
Granzymes are a family of serine proteases expressed by cytotoxic T lymphocytes and natural killer (NK) cells and are key components of immune responses to pathogens and transformed cells (1). Granzymes are synthesized as zymogens and are processed into mature enzymes by cleavage of a leader sequence. They are released by exocytosis in lysosome-like granules containing perforin, a membrane pore-forming protein. Granzyme B has the strongest apoptotic activity of all the granzymes as a result of its caspase-like ability to cleave substrates at aspartic acid residues thereby activating procaspases directly and cleaving downstream caspase substrates (2,3).
Perforin is a pore-forming protein that facilitates the entry of cytotoxic serine proteases, such as granzymes, into target cells (4). Perforin is primarily expressed in cytotoxic T lymphocytes and NK cells.
