title: Purification and characterization of cytotoxic factors in the venom of the Okinawa habu (Trimeresurus flavoviridis).
abstract: Two cytotoxic factors in the venom of Okinawa habu (Trimeresurus flavoviridis), a crotalid, have been purified and characterized. They had cell monolayer-disrupting activity against cells cultivated in vitro, but no proteolytic, hemorrhagic or direct hemolytic activity nor lethal toxicity. They were heat labile acidic proteins (isoelectric points 5.2 and 5.4) having similar molecular weights (approx. 14,000) and amino acid compositions. They were indistinguishable immunologically.
