Petrunkin and Petrunkin (1927, 1928) appear to be the first who studied the binding of GnHCl to gelatin and a mixture of thermally denatured protein from brain extract. . Greenstein (1938, 1939), however, appears to be the first to discover the high denaturing action of guanidinium halides and thiocyanates in following the liberation of sulfhydryl groups in ovalbumin and other proteins as a ...
Guanidine exists protonated, as guanidinium, in solution at physiological pH. Guanidinium chloride (also known as guanidine hydrochloride) has chaotropic properties and is used to denature proteins. Guanidinium chloride is known to denature proteins with a linear relationship between concentration and free energy of unfolding.
Phenol: The phenol used for biochemistry comes as a water-saturated solution with Tris buffer, as a Tris-buffered 50% phenol, 50% chloroform solution, or as a Tris-buffered 50% phenol, 48% chloroform, 2% isoamyl alcohol solution (sometimes called "25:24:1"). Phenol is naturally somewhat water-soluble, and gives a fuzzy interface, which is ...

TRIzol reagent contains guanidinium thiocyanate and phenol.. TRIzol is a widely used [1] chemical solution used in the extraction of DNA, RNA, and proteins from cells. The solution was initially used and published by Piotr Chomczyński and Nicoletta Sacchi in 1987.
Guanidinium thiocyanate can be used to deactivate a virus, such as the influenza virus that caused the 1918 "Spanish flu", so that it can be studied safely.. Guanidinium thiocyanate is also used to lyse cells and virus particles in RNA and DNA extractions, where its function, in addition to its lysing action, is to prevent activity of RNase enzymes and DNase enzymes by denaturing them.

A clinical chemistry analyzer; hand shows size. Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments.
