Abstract

An acidic phospholipase A2 (EC-I-PLA2) has been puri®ed from the Indian saw-scaled viper (Echis carinatus ) venom through a combination of column chromatography and electrophoresis. EC-I-PLA2 has a molecular weight of 16000 by SDS-PAGE. It was focussed between pH 4.2 and 4.8 by isoelectro focussing. EC-I-PLA2 was non-lethal to mice and devoid of neurotoxicity, myotoxicity, anticoagulant activity and cytotoxicity. It induced mild oedema in the foot pads of mice. The puri®ed PLA2 inhibited ADP, collagen and epinephrine induced human platelet aggregation and the inhibition was both dose and time dependent.
