Application

Urea is typically used for the denaturation of proteins and as a mild solubilization agent for insoluble or denatured proteins. It is useful for renaturing proteins from samples already denatured with 6 M guanidine chloride such as inclusion bodies. Urea may be used with guanidine hydrochloride and dithiothreitrol (DTT) in the refolding of denatured proteins into their native or active form.
Due to its low microbial and endotoxin limits, Urea cryst. Emprove^® Expert is especially suitable for high-risk applications.

Utilizada para la desnaturalización de proteínas y como suave agente de solubilización para las proteínas insolubles o desnaturalizadas. Útil para la renaturalización de proteínas de muestras ya desnaturalizadas con cloruro de guanidina 6 M como los cuerpos de inclusión. Puede utilizarse con clorhidrato de guanidina y ditiotreitol (DTT) en el repliegue de las proteínas desnaturalizadas a su forma nativa o activa.
