产品介绍：微囊藻毒素-LR属于环状七肽代谢产物微囊藻毒素类，由蓝绿藻铜绿微囊藻和其它藻类产生。应用该分析标准品可用于以下应用1.开发一种基于纳米生物碳（nBC）和抗微囊藻毒素-LR单克隆抗体（mAbs）的用于鉴定环境水样品中微囊藻毒素-LR的纸质免疫传感器；2.通过基于分子印迹聚合物和酶辅助颜色变化方法的侧流免疫色谱分析（LFICA）方法测定自来水样品中的微囊藻毒素-LR；3.采用单壁碳纳米管（SWNT）和dapoxyl 荧光染料制备的适体传感器进行自来水和血清样品中微囊藻毒素-LR的荧光检测；4.通过超高效液相色谱-质谱（UHPLC-MS）和高效液相色谱-可变波长紫外检测器方法（HPLC-VW-UVD）分析地表水样品以检测微囊藻毒素-LR；5.通过高效液相色谱和带电喷雾电离源的串联质谱（HPLC-ESI-MS/MS）测定地表水样品中的微囊藻毒素-LR。 Product introductionMicrocystins 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.ApplicationMicrocystin-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).
