Algal Toxin Analysis -
Microcystin, Cylindrospermopsin, Anatoxin-a, Saxitoxin

GreenWater Laboratories is a leader in cyanobacteria / algal toxin analysis. We have been analyzing water, tissues, and other biological matrices for algal toxins for over a decade. Toxin analyses includes microcystins, anatoxin-a/homoanatoxin-a, epi- and cylindrospermopsin, paralytic shellfish toxins (saxitoxins), BMAA, Lyngbyatoxin-A, aplysiatoxins, domoic acid and more. We currently utilize a variety of analysis techniques, from ELISA to LC-MS/MS, which allows us the sophistication to provide reliable data to our clients. We understand the importance of having accurate data so that important decisions can be made.

Algal Toxin Analysis

Phycological Services -
Algal Identification

We offer typical algal identification and enumeration services (with or without biovolume), but are also able to provide a non-quantitative potentially toxigenic cyanobacteria screening. This service allows for a quick TAT to determine if you have cyanobacteria and if toxin testing is recommended.

Algal Toxin Standards -
Purified Cyanotoxins

CyanoLab provides reference standards of common toxins produced by cyanobacteria. These standards are used for research, instrument calibration and toxicological testing. We use preparative HPLC to separate the toxins from the native cyanobacterial source.
