설명

일반 설명

Biological detergent
Agent for reversible denaturation of proteins. Special grade with low optical density for use in procedures where spectrometry is involved.

애플리케이션

Strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. This strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary.
