Detection of Perforin in Human PBMCs by Flow Cytometry. Human peripheral blood mononuclear cells (PBMCs) were stained with (A) Mouse Anti-Human Perforin Monoclonal Antibody (Catalog # MAB103853) or (B) isotype control antibody (MAB002) followed by Anti-Mouse IgG Allophycocyanin-conjugated Secondary Antibody (F0101B) and Mouse anti-Human CD56 Phycoerythrin-conjugated Monoclonal Antibody (FAB24086P). To facilitate intracellular staining, cells were fixed and permeabilized with FlowX FoxP3 Fixation & Permeabilization Buffer Kit (FC012). Staining was performed using our Staining Intracellular Molecules protocol.

Background: Perforin

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.
