Enzyme-linked immunosorbent assay (ELISA) plates prepared for cyanotoxin analysis, with labeled sample tubes in the background. ELISA is a laboratory technique used to detect and quantify specific antibodies, antigens, proteins, or hormones in biological samples.

Rotary evaporation system used to evaporate methanol from plant extracts, concentrating the sample so crystals containing cyanotoxins can form on the glassware.
