Soil Nitrite Reductase（S-NiR）Activity Assay Kit

Determination of Significance: Soil nitrite reductase (S-NiR) is one of the key enzymes in denitrification. It is a reductase produced by soil denitrifying bacteria. It can reduce NO 2- to NO. The activity reflects the conversion efficiency of nitrogen in the process of biodegradation, and provides a certain basis for the study of nitrogen conversion. Measurement Principle: Nitrite reductase can reduce NO 2- to NO, and reduce the NO 2- in the sample to participate in the diazotization reaction to produce a purple-red compound, that is, the change in absorbance at 540nm can reflect the activity of nitrite reductase in soil. Self Provided: Spectrophotometer/ Microplate reader, low temperature desk centrifuge, water-bath, adjustable transferpettor, mortar, micro glass cuvette/ 96-well flat-bottom plate, sieve (30-50 mesh, or smaller), ice and distilled water.
