Description

Microcystin CAS NO 77238-39-2 is a potent cyclic heptapeptide hepatotoxin produced by certain species of freshwater cyanobacteria. Its primary commercial and research significance lies in its role as a critical reference standard and analytical tool for environmental monitoring and toxicological studies. This compound is essential for laboratories and industries involved in water quality testing, food safety, and the development of detection methods for cyanobacterial blooms.

Application

• Environmental Monitoring & Water Safety: Used as a certified reference material (CRM) for the quantification of microcystin toxins in drinking water, recreational water bodies, and wastewater.
• Food Safety Testing: Serves as a critical standard in the analysis of shellfish, fish, and agricultural products for algal toxin contamination.
• Toxicological Research: Employed in academic and pharmaceutical research to study hepatotoxicity, carcinogenicity, and the biochemical mechanisms of protein phosphatase inhibition.
• Method Development & Validation: Essential for calibrating analytical instrumentation such as HPLC, LC-MS/MS, and ELISA kits to ensure accurate and reliable detection limits.
• Quality Control for Treatment Technologies: Used to test and validate the efficacy of water treatment processes in removing cyanotoxins.
• Regulatory Compliance: Supports testing to meet guidelines set by organizations like the WHO, EPA, and EFSA for maximum allowable toxin levels in water.

Quality Control

Our Microcystin is produced and handled under strict quality protocols to ensure the highest purity and stability for use as a reference standard. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation via spectroscopic methods, and quantification data. We support compliance with global regulatory frameworks for analytical standards.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below. Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation. The product is light-sensitive (store away from light).
