- Weitere Details:
- Perforin, originally cloned from mouse cytotoxic T-lymphocyte (CTL), is a 555-amino acid protein with a 21-amino acid signal peptide and is a potent cytolytic pore-forming protein. It is a specific marker of functionally active cytotoxic T-lymphocytes (CTLs) and natural killer (NK) cells. Fas ligand and perforin are the two key effector mechanisms in T cell-mediated cytotoxicity. These molecules mediate cytolysis of target cells by membrane damage and apoptosis, an important mechanism in the immune defense against tumors and virus infection. Perforin expression is constitutive on NK cells, but increases in resting XD8+ cytotoxic cells upon activation. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
