Overview

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

Biochemical and Physiological Mechanisms

Microcystin LA inhibits protein phosphatase type 2A and protein phosphatase type 3 more potently than protein phosphatase type 1 (order of potency PP2A > PP3 > PP1). Induces neutrophil-activating chemokines and extracellular reactive oxygen species, possi
