Tetra(3-methoxy-N-(PEG5-prop-2-ynyl)propanamide) Methane is a branched crosslinker with four terminal propargyl groups. The propargyl groups can react with azide compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage.

The Cylindrospermopsin plate kit is a competitive enzyme-labeled immunoassay. The Cylindrospermopsin sample extract and calibrators are pipetted into the test wells followed by the Cylindrospermopsin antibody into the test wells to initiate the reaction. During the 30 minutes incubation period, Cylin-drospermopsin from the sample and Cylindrospermopsin antigen compete for binding to the Cylindrosper-mopsin antibody. The Cylindrospermopsin antibody is captured on the walls of the test well. Following this 30-minute incubation, the contents of the wells are removed and the wells are washed to remove any unbound Cylindrospermopsin and free Cylindrospermopsin antibody. After wash, 1X HRP-conjugated Antibody#2 is added for 30 minutes incubation. The wells are washed afterwards, and a clear substrate is then added to the wells and any bound enzyme conjugate causes the conversion to a blue color. Following a 15-minute incubation, the reaction is stopped and the amount of color in each well is read. The color of the unknown samples is compared to the color of the calibrators and the Cylindrospermopsin concentration of the samples is derived.
