Glutathione (GSH) has been described for a long time just as a defensive reagent against the action of toxic xenobiotics (drugs, pollutants, carcinogens), both directly and as a cofactor for GSH transferases. Prepare appropriate volume of GST assay working reagent based on the number of samples to be measured. e organs (spleen, lymph nodes, brain, and pancreas) were quickly excised at the same time of the day (a.m. a.m.), mgs were immediately put into an Eppendorf microcentrifuge tube containing L of precipitating solution (mL containing . Prepare a solution of 0.5% MPA in 1X Assay Buffer and mix. Use only enough for immediate applications (eg. Preparation of 1 mmol/L GSH standard solution Dissolve a vial of reagent 5 with 10 mL of reagent 6 application solution fully. The discipline of developmental toxicology is an integration of concepts, models, and methodologies based heavily on the superimposition of toxicology principles upon the science of developmental biology.
