Cylindrospermopsin Detection Kit (Rapid – Freshwater Streams and Source Water)

Attogene’ s Cylindrospermopsin Lateral Flow Kit can be used to detect Cylindrospermopsin in source water samples.

Format: Rapid-Water – Run Time: 30 Minutes, enough to run two samples (undiluted and a 10 fold dilution) and negative control.

Cylindrospermopsin (CYN) is a potent cyanotoxin synthesized by select species of cyanobacteria, prominently including Cylindrospermopsin raciborskii. It belongs to the tricyclic alkaloid class, exhibiting a molecular weight of approximately 415 Da. Structurally, cylindrospermopsin features an uracil ring fused with a hydantoin moiety, alongside a guanidino group, attributes that render it highly soluble and polar in aqueous environments.

Cylindrospermopsin is notorious for its profound toxicity towards aquatic organisms and its potential threat to human health through exposure via contaminated water and food sources. Consequently, rigorous monitoring protocols are essential in regions prone to cyanobacterial blooms, where cylindrospermopsin can accumulate in freshwater reservoirs and other aquatic habitats. In recognition of these risks, regulatory bodies such as the United States Environmental Protection Agency (EPA) have implemented an action level guideline. As of 2019, EPA 10-day drinking water health advisory for cylindrospermopsin recommended a threshold of 0.7 parts per billion (ppb), or 700 parts per trillion (ppt) for children under the age of six, and 3 parts per billion, 3000 parts per trillion for anyone older, to effectively manage cylindrospermopsin levels. This precautionary measure aims to uphold both environmental sustainability and public health integrity by minimizing exposure risks.  The EPA has also drafted a human health recreational water quality criterion to protect human health at 8,000ppt.

EPA 10-Day drinking water Health Advisories for Cylindrospermopsin:

Do not Drink – 3.0 μg/L for school age children to adults

Do Not Use – 20 μg/L

EPA Draft Human Health Recreational Ambient Water Quality Criteria to protect human health: 8 μg/L
