I am presently working with H9C2 cell. Now, I want to quantify glutathione peroxidase enzyme after exposure of hypoxic condition to H9C2 cells. So, which methods should I have to use?
As “an excellent document" of 1984 is weakly linked to now-a-day cellular measurements of GPx, I would like to recommend the BioVision’s Glutathione Peroxidase Assay Kit (Catalog #: K762), which measures glutathione peroxidase (GPx) activity through a coupled reaction with glutathione reductase (GR). In the assay, GPx reduce Cumene Hydroperoxide, and oxidize GSH to GSSG. The generated GSSG is reduced to GSH with consumption of NADPH by GR. The decrease of NADPH is proportionally to GPx activity in the reactions. The decrease of NADPH can be easily measured by absorbance at 340 nm. The assay can be used to measure all of the glutathione dependent peroxidases in plasma, erythrocyte lysates, tissue homogenates, and cell lysates with detection sensitivity ~ 0.5 mU/ml of GPx in samples.
