Description

Microcystin Ly is a potent cyclic heptapeptide hepatotoxin produced by certain species of freshwater cyanobacteria. This compound is of critical importance for research and diagnostic applications, particularly in the study of toxic algal blooms and their impact on environmental and public health. It serves as a vital analytical standard and reference material for laboratories in the environmental monitoring, water treatment, and toxicology sectors, enabling accurate detection, quantification, and risk assessment of cyanobacterial toxins in water supplies.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical methods like HPLC-MS/MS and ELISA for microcystin detection.
• Environmental Research & Monitoring: Critical for studying cyanobacterial bloom dynamics, toxin production, and ecological impact in freshwater systems.
• Toxicological Studies: Used in laboratory research to investigate the mechanisms of hepatotoxicity, including protein phosphatase inhibition and oxidative stress.
• Water Quality & Safety Testing: Essential for developing and verifying testing protocols used by public health agencies and water treatment facilities.
• Diagnostic Kit Development: Serves as a key antigen and calibrator in the production of immunoassay kits for rapid field or lab-based toxin screening.
• Regulatory Compliance: Supports compliance testing against international guidelines for microcystin levels in drinking and recreational water.
