Microcystin-LR

Product introduction: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.Application:Microcystin-LR may be used as an analytical reference standard for the determination of the analyte in surface water samples using high-performance liquid chromatography coupled to tandem mass spectrometry with electrospray ionization source (HPLC-ESI-MS/MS).
