In the less extensive technique of equilibrium unfolding, the fractions of folded and unfolded molecules (denoted as and , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the unfolded state, e.g., by adding a denaturant such as guanidinium hydrochloride or urea.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

The RNA is then precipitated in an alcohol (right). Acid guanidinium thiocyanate-phenol-chloroform extraction (abbreviated AGPC) is a liquid–liquid extraction technique in biochemistry and molecular biology. It is widely used for isolating RNA (as well as DNA and protein in some cases).
A chevron plot is a way of representing protein folding kinetic data in the presence of varying concentrations of denaturant that disrupts the protein's native tertiary structure. The plot is known as "chevron" plot because of the canonical v , or chevron shape observed when the logarithm of the observed relaxation rate is plotted as a function ...
Denaturation midpoint of a protein is defined as the temperature (T m) or concentration of denaturant (C m) at which both the folded and unfolded states are equally populated at equilibrium (assuming two-state protein folding). T m is often determined using a thermal shift assay.
The Cohn process, developed by Edwin J. Cohn, is a series of purification steps with the purpose of extracting albumin from blood plasma.The process is based on the differential solubility of albumin and other plasma proteins based on pH, ethanol concentration, temperature, ionic strength, and protein concentration.
We know sushi is Japanese, but there are plenty of U.S.-born rolls that we have come to adore. The California roll might be the top on your list, but if you’ve never had an Alaska roll, you’re ...
Denaturation (biochemistry), a structural change in macromolecules caused by extreme conditions; Denaturation (fissile materials), transforming fissile materials so that they cannot be used in nuclear weapons; Denaturation (food), intentional adulteration of food or drink rendering it unfit for consumption while remaining suitable for other uses
