glutathione protein carbonyls Full article: carbonylation: molecular mechanisms, biological implications, and analytical approaches Protein Carbonylation - an overview

This assay is an adaptation of the method of Paglia and Valentine

Nramp5 , a key transporter protein for cadmium uptake by the root system, is located at the plasma membrane and is highly expressed in the root maturation zone, responsible for the transport of cadmium from the outside into the root cells (Sasaki et al., 2012

If you think you will be purifying the same exact protein again in the future, then you should rinse your elution buffer out with a few column volumes of deionized water (dIH 2 O), and then store the beads in 20% ethanol until youre ready to use them again

Lastly, glutathione production is directly linked to the amount of cysteine available in cells
