Description

Microcystin Ym CAS NO 101043-35-0 is a potent cyclic heptapeptide hepatotoxin produced by certain species of freshwater cyanobacteria. This compound is of critical importance as a reference standard and analytical tool for environmental monitoring, toxicological research, and water safety assessment. It is primarily needed by analytical laboratories, research institutions, and environmental agencies involved in the detection and quantification of cyanotoxins in water supplies, algal blooms, and biological samples.

Application

• Environmental Monitoring & Water Safety: Used as a certified reference material (CRM) for the calibration and validation of analytical methods (e.g., LC-MS/MS, ELISA) to detect and quantify microcystin contamination in drinking water, recreational water bodies, and algal bloom samples.
• Toxicological Research: Serves as a precise biochemical tool for studying the mechanisms of hepatotoxicity, including the inhibition of protein phosphatases PP1 and PP2A, and for evaluating the chronic health effects of cyanotoxin exposure.
• Method Development & Validation: Essential for developing, optimizing, and accrediting new analytical protocols in compliance with guidelines from organizations like the WHO, EPA, and ISO.
• Quality Control & Assurance: Acts as a system suitability check and positive control in laboratory quality control programs to ensure the accuracy and reliability of routine cyanotoxin analysis.
• Forensic Analysis & Regulatory Compliance: Supports investigations into poisoning events in wildlife, livestock, or humans and aids in regulatory enforcement by providing definitive identification of the toxin.
• Production of Antibodies & Test Kits: Utilized as a pure antigen for the development and production of specific antibodies used in immunoassay test kits and biosensors.

Quality Control

Our Microcystin Ym is produced and handled under strict quality protocols to ensure the highest purity and stability for critical analytical and research applications. Each batch is characterized using advanced techniques including High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided, supporting compliance with relevant research and environmental monitoring standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability. Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation.
