Orderable Test Description
Perforin is a protein found in cytoplasmic granules of cytotoxic T-lymphocytes (CTLs). CTLs bind to cells that express foreign antigens and induce them to lyse. Perforin expression is significantly induced in CD8 positive T-cells, but to lesser extent in gamma/delta T-cells and NK cells. This antibody may be of value in the detection of perforin in CTLs in severe cases of graft versus host disease, chronic renal rejection and peripheral T-cell lymphomas. In addition, perforin antibody may also be useful for the detection of NK cell lymphomas, all of which express the perforin protein.
