Description

Toxin Iii, Cyanobacterium is a potent cyanobacterial neurotoxin, specifically a saxitoxin analog, identified by CAS No. 118389-25-6. This compound is of critical importance for research into paralytic shellfish poisoning (PSP) and the development of detection methods and potential therapeutics. It serves as a vital reference standard and research tool for toxicologists, marine biologists, and analytical chemists working in environmental monitoring, food safety, and neuropharmacology.

Application

• Analytical Reference Standard: Primary calibration standard for the precise quantification of saxitoxin analogs in complex matrices via HPLC, LC-MS, or ELISA methods.
• Toxicological Research: Used in studies to investigate the mechanism of action of voltage-gated sodium channel blockade and the pathophysiology of paralytic shellfish poisoning.
• Environmental Monitoring: Critical component in method development and validation for monitoring cyanobacterial and algal blooms in freshwater and marine ecosystems.
• Food Safety Testing: Employed as a certified reference material (CRM) to ensure the accuracy and reliability of shellfish toxicity testing programs worldwide.
• Biomedical Research: Tool for studying ion channel function and for the screening and development of potential antidotes or channel blockers.
• Diagnostic Kit Development: Essential for the production and quality control of rapid test kits and immunoassays designed for on-site toxin detection.
