I would like to ask about the method to measure (oxidized and total glutathione concentration) from Glutathione Assay Kit (CS0260 Sigma-Aldrich).
It is mentioned in (kit leaflet - product description) that the kit could measure the level of total glutathione (GSH + GSSG), but in (Results / Calculations), it is only mentioned the equation of GSH in an unknown sample!
So, how to calculate the oxidized glutathione, could this kit do this function or not?
