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.

Attogene’s Microcystin Test Kit (Rapid – Lab) can be used to detect microcystins in liquid samples.
The most frequently reported cyanobacterial toxins are the hepatotoxic microcystins (MCs). MCs are peptides with a molecular weight ranging from 900 to 1,100 Da. They consist of seven amino acids of which the two terminal amino acids of the linear peptide are condensed to form a cyclic compound.
A tiered notification system which takes different actions based on different numeric thresholds for microcytin-LR concentrations in recreational waters has been developed. This is guidance that allows states to take various actions—such as posting information about harmful algal blooms (HABs), issuing a recreational public health advisory, or temporarily closing recreational waters through a no contact advisory—depending on the severity of the bloom event.
Microcystin-LR
Informational sign postings about HABs at recreational waters: < 6 μg/L
Recreational public health advisory: 6 μg/L
Elevated recreational public health advisory (e.g. no contact): 20 μg/L
Screening of Algae Toxins Microcystins and Nodularins
Format: 10 tests (5 tests/5 control)
