Anti-Perforin FITC

• Description:

  Perforin is a 70 kDa cytolytic protein with structural and functional similarities to complement component 9 (C9) . It is stored in cytoplasmic granules of cytotoxic T cells and NK cells and after its release it forms transmembrane pores in the target cells to kill it. As perforin is a key effector molecule for cell-mediated cytolysis, defects of its gene can cause severe disorders.
