Abstract Background The lumen of the endoplasmic reticulum (ER) acts as a cellular Ca2+ store and a site for oxidative protein folding. which is controlled by the reduced glutathione (GSH) and glutathione-disulfide (GSSG) redox pair. Although depletion of luminal Ca2+ from the ER provokes a rapid and reversible shift towards a more reducing poise in the ER. the underlying molecular ba... https://www.spidertattooz.com/The-GelBottle-Inc-BIAB-Gel-Polish-Baby-67oz-p16988/
