Enzytec™ Alpha-amino Nitrogen is a colorimetric assay for the determination of alpha-amino nitrogen in foodstuff and other sample materials.
General Information
Primary amino groups are derivatized by o-phthaldialdehyde (OPA) and N-acetylcysteine (NAC) to give isoindoles.
In optimized conditions, isoindoles give a chromogenic complex with a max. absorbance at 340 nm, proportional to the concentration of alpha-amino nitrogen in the sample.
