CAS号：9001-84-7级别：BR来源：Crotalus durissus terrificus venomSpecific activity：≥20u/mg protein活力定义：One Unit releases one micromole of acid from soybean lecithin per minute at 25℃, pH 8.9产品描述：Phospholipase A2 is a member of the class of heat-stable, calcium-dependent enzymes catalyzing the hydrolysis of the 2-acyl bond of 3-n-phosphoglycerides. The enzyme has a molecular weight of 30,000 daltons. Phospholipase A2 is activated by Ca2+. It is inhibited by zinc, barium, and manganese ions. Activity values for phospholipase A preparations which are derived from titrimetric assay procedures can be quite dependent on source and type of lecithin, its preparation as a substrate emulsion, other components of the reaction mixture, and the method and instrumentation used性状(以下信息仅供参考)：粉末。EC3.1.1.4用途：本品仅供科研，不得用于其它用途保存：-20℃
