Perforin: Lysates

Perforin (PRF1) is a 70 kD cytolytic protein that is the major protein constituent of cytoplasmic granules of cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells. Specifically, perforin enters the target cell's plasma membrand and creates a intercellular pore to mediate targeted cell lysis. PRF1 antibodies are useful tools for lysis research on both CTLs and NK cells.
