描述: 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.

供应商: IKA JANKE KUNKEL
描述: Digital block heaters which hold from one up to four aluminum blocks, provide precise temperature control in small vessels. The PT1000 temperature sensor allows temperature control directly in the sample vessel. It is used with PCR tubes, PCR strips, Greiner tubes, microplates and cuvettes. The block heaters are ideal for melting and boiling point determination, enzyme reactions, incubation and activation of cultures, immunoassays, DNA denaturation, culture media tests, coagulation tests, blood/urea nitrogen determinations and <i>in situ</i> hybridisations.
