Accelerate your Research with Recombinant Enzymes - Robust Data for Publishing your Next Study

Many researchers are investigating various aspects of nitrate, which sits in a central position in plant and algal metabolism, as well as in water pollution leading to eutrophication and impacts on species diversity in natural environments. Whether your team is analyzing thousands of samples per day in an automated laboratory system or spot-checking levels on-site, we have a kit formulated for you. We currently offer enzymes and enzyme-based test kits for the analysis of nitrate and phosphate in the laboratory or out in the field, and will soon be offering enzymes for the analysis of glycerol, galactose, and ethanol.

Our assays are simple in design - a small volume of sample is mixed with a buffer containing the enzyme, co-factor is added, then reaction occurs. For our phosphate method, measurement at 360 nm using a UV-capable spectrophotometer or microplate reader yields results immediately following the enzymatic reaction. For our nitrate assay, Griess chemistry is carried out following the enzymatic reduction for the formation of an AZO dye and then absorbance is determined spectrophotometrically at 540 nm. These kits can also be used to perform Total Nitrogen and Total Phosphorus analysis by using them in conjunction with a Persulfate Digestion. Inquire with us today for a custom kit design for your team or to learn more about our enzymes in the research and development stages.
