Detection principle

Reduced GSH can react with Dinitrobenzoic acid (DNTB) to form a yellow complex which can be detected by colorimetric assay at 405 nm and calculate the reduced GSH content indirectly.

Dilution of sample

It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (2-100 μmol/L).

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

Sample type

Dilution factor

Human serum


Human plasma


10% Mouse brain tissue homogenization


10% Mouse liver tissue homogenization


Hela cell  homogenization0.999 mgprot/mL


Rat serum


Rat plasma


Mouse serum


10% Carrot tissue homogenization


293T supernatant


Note: The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4).
