Background

Perforin is a pore forming, cytolytic protein that is a component of cytolytic T-cell and NK cell granules.  Perforin activates clathrin- and dynamin-dependent endocytosis, which removes perforin and granzymes from the plasm membrane to early endosomes, preserving outer membrane integrity.  Perforin facilitates granzyme uptake and avoids the proinflammatory necrotic death of a membrane-damaged cell.  Defects in the Perforin gene results in Familial hemophagocytic lymphohistiocytosis (FHL).  Perforin-based effector systems are involved not only in the lysis of abnormal cells but also in the down-regulation of cellular immune activation.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
