GreenWater Laboratories/CyanoLab represents one of the first commercial laboratories with the expertise and experience to perform and interpret algal toxin analysis. All analyses are conducted by professionals in the field of chemistry with confirmatory analysis available upon request (i.e. LC/MSn).
ELISA:
Enzyme-Linked Immunosorbent Assays, or ELISAs, are very popular screening assays that provide limited quantitative information for specific groups of algal toxins. ELISAs typically have the ability to detect toxins at low levels for both surface and drinking waters. It should be noted that ELISAs are also prone to sample matrix interference that may confound results, leading to erroneous conclusions. It is important to have the ability to verify any positive ELISA responses with other techniques, such as HPLC coupled with PDA, FL or MS.
Toxins analyzed with ELISA:
- Microcystins/Nodularin
- Paralytic Shellfish Toxins (saxitoxins)
- Cylindrospermopsin
- Brevetoxins
- Okadaic Acid
GWL/CL currently maintains and operates high performance liquid chromatography (HPLC) systems with photodiode array (PDA), fluorescence (FL), and mass spectrometry (MSn) detection. This provides GWL/CL the ability to report data with a high level of confidence as well as the ability to supply confirmatory analysis on ELISA data.
Toxin analyzed with HPLC/MS
- Microcystins (e.g. -RR, -YR, -LR, -dmLR, -LY, -[D-Leu]1LR, -LA, -LW, -LF)
- Cylindrospermopsin
- Anatoxins
- Paralytic Shellfish Toxins (Saxitoxins)
- BMAA
- Domoic Acid
- Lyngbyatoxin-A
- Aplysiatoxin and Debromoaplysiatoxin

Other toxin analyses are available. Please call regarding your specific needs.
Rapid Turnaround Times are available on all toxin analysis, with results provided as soon as 24 hours after receipt. Please call for rapid TAT requests.
