Attogene’s Carbon Dioxide Enzymatic Assay Kit is a simple, direct method for measuring Carbon Dioxide levels in the environment. The assay uses a coupled enzyme assay to detect CO2 (as HCO3-) as follows. In the first step, the bicarbonate condenses with phosphoenol pyruvate to form oxalate (and phosphoric acid); this reaction is catalyzed by the enzyme Phosphoenolpyruvate Decarboxylase, PEPC. The oxalate is then enzymatically reduced by the enzyme Malate Dehydrogenase (using an NADH cofactor) to form malate and NAD+.

Propargyl-PEG4-Ms has an alkyne group and a mesylate group. The mesylate group is a sulfonate ester for nucleophilic substitution reactions (SN2). The alkyne group can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environments. Reagent grade, for research use only.

Attogene’s Microcystin Test Kit (Rapid – Drinking Water) can be used to detect microcystins in water to as low as 0.1ppb; highly sensitive, rapid, robust screening kit for microcystins and nodularins.
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 thresholds for microcytin-LR concentrations in drinking waters has been developed. This is guidance that allows states to take various actions.
For the rapid screening of microcystins in drinking water samples at or above 0.1 ppb. Samples requiring regulatory action should be confirmed by ELISA, HPLC, or other conventional methods.
To protect consumers from adverse health effects caused by these toxins, the World Health Organization (WHO) has proposed a provisional upper limit for Microcystin-LR of 1.0 ppb (μg/L) in drinking water.
The U.S. Environmental Protection Agency (EPA) has also established guidelines for Microcystins in drinking water:
-For children below school age, 0.3 μg/L (ppb)
-For all other age groups, 1.6 μg/L (ppb)
