- Specific activity：≥200u/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

本計算器可幫助您計算出特定溶液中溶質的質量、溶液濃度和體積之間的關系，公式為：
質量 (mg) = 濃度 (mM) x 體積 (mL) x 分子摩爾量 (g/mol)
