磷脂酶A2（PLA2）根据依赖Ca2+的PLA2在体内的分布。可分为分泌型（PLA2-Ⅰ和PLA2-Ⅱ）和胞质型（PLA2-Ⅲ和PLA2-Ⅳ）两种。PLA2-Ⅱ是重症胰腺炎出现一系列并发症的早期标志物，作为急性时相反应介质，与重症胰腺炎的发展密切相关。因此，测定PLA2-Ⅱ对细菌感染性坏死性胰腺炎、重症AP并发多器官功能衰竭等具有重要的识别作用。

产品介绍

[产品名称]	磷脂酶A2
[规格]	BR，20u/mg，响尾蛇毒液
[包装]	1毫克

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

其他名称：磷酯酶A2

：BR

来源：Crotalus durissus terrificus venom

Specific 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
