The Microcystin Strip Test Kit is a rapid immunochromatographic test, designed solely for use in the qualitative screening of microcystins and nodularins in RW. A rapid cell lysis step (QuikLyseTM) performed prior to testing is required to measure total microcystins (dissolved or free, plus cell bound). The Microcystin Strip Test Kit provides only preliminary qualitative test results. If necessary, positive samples can be confirmed by ELISA, high-pressure liquid chromatography (HPLC) or other conventional methods. The test is designed for field use, requiring no instrumentation or other equipment, no power sources, and no refrigerated storage. The test is based on the recognition of microcystins, nodularins and their variants by specific antibodies. The toxin conjugate competes for antibody binding sites with microcystins/nodularins that may be present in the water sample.
