Rat Anti-Mouse Perforin Antibody (S-R644)

Perforin is a crucial protein involved in the immune response, primarily produced by cytotoxic T lymphocytes and natural killer cells. It functions by forming pores in the membranes of target cells, such as virus-infected or cancerous cells. Once released from immune cells, perforin molecules aggregate and insert into the target cell membrane, creating channels that disrupt the cell's osmotic balance, leading to cell lysis and death. This mechanism is essential for eliminating harmful cells and maintaining the body's overall health.
