Description

Microcystin Yr is a potent cyclic heptapeptide hepatotoxin produced by certain freshwater cyanobacteria. This compound is of critical importance for environmental monitoring, toxicological research, and the development of detection methods for cyanobacterial blooms. It serves as a vital reference standard and analytical tool for researchers, regulatory agencies, and water quality testing laboratories globally.

Application

• Analytical Reference Standard: Primary use as a certified standard for the quantitative analysis of microcystins in water samples via HPLC, LC-MS/MS, and ELISA techniques.
• Toxicological Research: Used in laboratory studies to investigate the mechanisms of hepatotoxicity, including protein phosphatase inhibition and oxidative stress.
• Method Development & Validation: Essential for developing, calibrating, and validating new analytical methods for cyanotoxin detection in environmental and drinking water.
• Quality Control & Assurance: Employed in the manufacturing of test kits and immunoassays to ensure accuracy and reliability in microcystin detection.
• Regulatory Compliance Testing: Supports laboratories in monitoring water bodies to comply with national and international guidelines for cyanotoxin levels (e.g., WHO, EPA).
• Academic & Institutional Research: Fundamental reagent for studies in ecotoxicology, phycology, and public health related to harmful algal blooms (HABs).
