Urea 8 mol/l in aqueous solution, Proteomics Grade

Urea 8 mol/l in aqueous solution, Proteomics Grade

Supplier: VWR Chemicals

A convenient pre-mixed solution that is easily diluted for buffer preparation under denaturing conditions.Commonly used to denature nucleic acids for electrophoresis and to study the secondary and tertiary structure of proteins. Effective for maintaining DNA in a highly denatured state during sequencing protocols, urea is also useful for accelerating the activity of Proteinase K digestions.

Guanidinium hydrochloride ≥99%, white crystalline powder, Ultrapure

Guanidinium hydrochloride ≥99%, white crystalline powder, Ultrapure

Supplier: MP BIOMEDICALS

Guanidine Hydrochloride is a protein denaturant and thus having an important role in molecular weight determinations.
Guanidine Hydrochloride is a 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. Guanidine HCl is used in the isolation of RNA to dissociate the nucleoprotein into its nucleic acid and protein moieties. It is an inhibitor of RNase. Highly concentrated (6 - 8 M) Guanidine HCl solutions are used to denature native globular proteins. It apparently disrupts hydrogen bonds which hold the protein in its unique structure. However, there also is evidence suggesting that guanidine hydrocholoride may disrupt hydrophobic interactions by promoting the solubility of hydrophobic residues in aqueous solutions.
