N-(Acid-PEG4)-N-bis(PEG4-Propargyl) is a trifunctional PEG linker that combines a t-butyl ester with two terminal alkynes. The alkynes can be applied in copper-click chemistry with azides to form stable triazole linkages with a target molecule, while the acid can be reacted with amines or alcohols to form stable amides or esters.

The Saxitoxin (PSP) ELISA Kit is a competitive ELISA for the quantitative analysis of saxitoxin in shellfish samples. This kit can be used for rapid test of Saxition in samples such as mussels and lobster tomalley.
The Saxitoxin (PSP) ELISA Kit uses a polyclonal antibody that binds both saxitoxin and a Saxitoxin-enzyme conjugate. Saxitoxin in the sample competes with the Saxitoxin-enzyme conjugate for a limited number of antibody binding sites.
