CheKine™ Micro Soil Nitrite Reductase (S-NiR) Activity Assay - 48 T/48 S

Soil Nitrite Reductase: Soil nitrite reductase is one of the key enzymes involved in denitrification, catalyzing the reduction of nitrite (NO2-) to nitric oxide (NO). Its activity reflects the efficiency of nitrogen transformation during biological degradation processes and provides valuable insights into the patterns of nitrogen conversion. CheKine™ Micro Soil Nitrite Reductase (S-NiR) Activity Assay Kit is designed to quantify nitrite reductase activity in soil samples. The assay principle is based on the enzyme's ability to reduce NO2- to NO, which decreases the concentration of NO2- available for diazotization reactions that produce a purple-red compound. The change in absorbance at 540 nm directly correlates with the activity of nitrite reductase in the soil sample.
