概述

用于蛋白质变性以及作为不溶性或变性蛋白的温和增溶剂。可用于从已由 6M 盐酸胍变性的样品(如包涵体)复性蛋白质。可与盐酸胍和二硫苏糖醇 (DTT) 一起用于复性变性蛋白以恢复其天然或活性形式。

Used for the denaturation of proteins and as a mild solubilization agent for insoluble or denatured proteins. Useful for renaturing proteins from samples already denatured with 6 M guanidine chloride such as inclusion bodies. May be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form.
