Abstract
A novel serine esterase produced by cytotoxic T lymphocytes is insolated and characterized. The protein appears to be membrane bound and has a reduced apparent molecular weight of about 28,000 daltons. Inhibition of the esterase correlates with inhibition of the cells' cytolytic activity. The serine esterase is useful in making antibody and as a target for the inhibition of cytolytic activity by T-lymphocytes, both in vivo and in vitro.
