Propargyl-PEG9-amine has a propargyl group and an amine group. The amine group reacts with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) to form amide bonds. The propargyl group reacts with azides to form triazole linkage with the presence of copper as a catalyst. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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)
Not provided: Water Sample Bottles
Run Time: 10 Minutes
Sulfo DBCO-PEG4-Amine is a water-soluble carboxyl-reactive building block with extended PEG spacer arm. In the presence of of activators (e.g. EDC, or HATU), this reagent can be used to derivatize carboxyl groups or activated esters (e.g. The NHS ester) through a stable amide bond. The hydrophilic sulfonated spacer arm greatly improves water solubility of DBCO derivatized molecules and a provides a long and flexible connection. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
