For research use only.

Detection Principle Nitrite reductase (NiR) in the sample can reduce NO2- to NO, so that the NO2- involved in the diazotization reaction to produce purplish red compounds is reduced, that is, the change of absorbance value at 540 nm can reflect the activity of the sample nitrite reductase.
Sample Type Plant tissue
Detection Method Colorimetric method
Detection Instrument Microplate reader (530-550 nm, optimum wavelength: 540 nm)
Research Area Plant Physiology Series

The recommended dilution factor for different samples is as follows (for reference only):

Sample Type Dilution Factor
10% Corn tissue homogenate 1
10% Cabbages tissue homogenate 1
10% Green pepper tissue homogenate 1
10% Radish tissue homogenate 1

The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4). For the dilution of other sample types, please do pretest to confirm the dilution factor.
