title: [Basic phospholipase from the venom of Naja nigricollis is cytotoxic].
abstract: The basic phospholipase A2 purified from the venom of Naja nigricollis (Institut Pasteur), possesses an intense cytotoxic activity toward fetal cells from FL strain. At a concentration equal to 1.6 x 10(-6) M, the PLA2 lyses 50% of the cells present in a suspension containing 3.5 x 10(6) cells per millilitre. Other PLA2 from various origins do not exhibit such cytotoxic activity.
