产品简介：
从淡水蓝藻铜绿微囊藻中分离出的环七肽毒素。蛋白磷酸酶1（pp1）和蛋白磷酸酶2a（pp2a）的有效抑制剂。不像秋葵酸，微囊藻毒素lr对PP1（IC50=1.7 nM）和PP2A（IC50=40 PM）均有效。以两步反应机制与磷酸酶反应，包括催化亚单位的快速结合和失活，以及较慢的共价相互作用。对蛋白激酶无影响，有助于降低蛋白激酶检测中污染磷酸酶活性的影响。微囊藻毒素lr，铜绿微囊藻溶于DMSO中也可用。
产品用途：
微囊藻毒素-lr，铜绿微囊藻是一种有效的蛋白磷酸酶1（pp1）和蛋白磷酸酶2a（pp2a）抑制剂。primary target IC50：1.7 nM and 40 pM against PP1 and PP2A, respectively
体外研究：
Microcystins are toxic molecules produced by cyanobacterial blooms due to water eutrophication. Microcystin-LR proves to be a potent inhibitor of type 1 (IC50=1.7 nM) and type 2A (IC50= 0.04 nM) protein phosphatases. Microcystin-LR inhibits the activity of both type 1 and type 2A phosphatases >10-fold more potently than okadaic acid under the same conditions. Type 2A protein phosphatases in dilute mammalian cell extracts are found to be completely inhibited by 0.5 nM microcystin-LR while type 1 protein phosphatases are only slightly affected at this concentration.
