Soil Nitrate Reductase (S-NR) Assay Kit

Soil Nitrate Reductase (S-NR) Assay Kit

S-NR catalyzes the reduction of nitrate to nitrite in soil, which is a key enzyme for soil nitrate nitrogen reduction. Studying the activity of S-NR is of great significance for rational fertilization and reducing nitrogen loss.

S-NR catalyzes the reduction of nitrate to nitrite, NO3ˉ +NADH+H+→ NO2ˉ +NAD+ +H2O; The resulting nitrite can quantitatively form red azo compounds with p-aminobenzene sulfonic acid and α-naphthamine under acidic conditions. The resulting red azo compound has a maximum absorption peak at 540 nm and can be determined by spectrophotometry.
