Scientific Data Images for Human Perforin Antibody

Perforin in SW480 Human Cell Line.

Perforin was detected in immersion fixed SW480 human colorectal adenocarcinoma cell line using Rabbit Anti-Human Perforin Monoclonal Antibody (Catalog # MAB103854) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; NL004) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.

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.
