產(chǎn)品介紹

[產(chǎn)品名稱]	磷脂酶A2
[規(guī)格]	BR，20u/mg，響尾蛇毒液
[包裝]	1毫克

英文名稱：PLA2；Lecithinase A；Phosphatidylcholine 2-acylhydrolase；Phospholipase A2

其他名稱：磷酯酶A2

：BR

來源：Crotalus durissus terrificus venom

Specific activity：≥20u/mg protein

活力定義：One Unit releases one micromole of acid from soybean lecithin per minute at 25℃, pH 8.9

產(chǎn)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
