Description

Application

Guanidine hydrochloride is used in RNA isolation to dissociate nucleoproteins and inhibit RNase.

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.

Packaging

1 kg in poly bottle

2, 10, 25 kg in poly drum

Caution

May agglomerate upon storage. The quality of the product does not appear to be affected and solutions prepared from the free-flowing and lumpy guanidine hydrochloride appear identical. For free-flowing material, please see our Redi-Dri free-flowing product number RDD001.

Preparation Note

In order to make an 8M solution in water, one must heat the solution to 35 °C for approximately 30 minutes.
The maximum solubility of guanidine hydrochloride in water at room temperature is approximately 6M.
