Denaturation is the process by which foods or liquids are made unpleasant or dangerous to consume; it is done by adding a substance known as a denaturant. Aversive agents —primarily bitterants and pungent agents —are often used to produce an unpleasant flavor.
A larger amount of one sample is used with perpendicular, while a smaller amount of many samples are used with parallel TGGE. Once the gel has been run, the gel must be stained to visualize the results. While there are a number of stains that can be used for this purpose, silver staining has proven to be the most effective tool. [6]
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, radiation, or heat.

Samples are subjected to either temperature ramps or gradients of chemical denaturant, and the intrinsic fluorescence is measured and fit to determine the melting point (T m). Applications include formulation ranking, protein engineering (comparing mutants to wild type), and ligand binding (quantification of affinity constants).
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.
