---|---|
英文名称 | Microcystin-LA |
别名 | Biotoxin;Algae bloom toxin;Cyanobacterial toxin |
英文别名 | Biotoxin;Algae bloom toxin;Cyanobacterial toxin |
应用 | Microcystin LA 是一种天然毒素,Microcystin LA 通过抑制丝氨酸-苏氨酸蛋白磷酸酶 PP1 (IC50=0.3 nM) 和 PP2A (IC50=0.3 nM) 来发挥其细胞毒性作用。 |
规格或纯度 | 10ug/ml in methanol |
运输条件 | 干冰运输 |
生化机理 | 微囊藻毒素 LA 抑制蛋白磷酸酶类型 A 型和蛋白磷酸酶 3 类型的能力强于蛋白磷酸酶 1 类型(效价顺序 PP2A > PP3 > PP1)。诱导中性粒细胞活化趋化因子和胞外活性氧,可能的机制是其肝毒性作用。 |
一般描述
产品介绍:
微囊藻毒素是一种单环小分子多肽,由 7 个氨基酸通过肽键连接而成。是一种具有肝毒性和促癌属性的青毒素。鱼腥藻属、 丝囊藻属、 微胞藻属 和 浮丝藻属等几个藻属产生微囊藻毒素。微囊藻毒素有四种同源物,即-LR、-LA、-YR 和-RR。
产品用途:
Microcystin LA inhibit PP1 and PP2A quite potently and specifically relative to other known phosphatases, such as PP2B (calcineurin), PP2C, and the tyrosine phosphatases
Product introduction:
Microcystin is a small, monocyclic peptide, composed of seven amino acids connected via peptide bonds. It is a cyanotoxin with hepatotoxic and tumor promoting properties. Several algal genera like Anabaena, Aphanizomenon, Microcystis and Planktothrix produce microcystin.[2] Microcystin has four congeners namely, -LR, -LA, -YR and -RR.
Application:
Microcystin LA inhibit PP1 and PP2A quite potently and specifically relative to other known phosphatases, such as PP2B (calcineurin), PP2C, and the tyrosine phosphatases
