The most famous example is the hyperchromicity of DNA that occurs when the DNA duplex is denatured. [1] The UV absorption is increased when the two single DNA strands are being separated, either by heat or by addition of denaturant or by increasing the pH level. The opposite, a decrease of absorbance is called hypochromicity.
Diagram. The technique was first described by Semisotnov et al. (1991) [14] using 1,8-ANS and quartz cuvettes. 3 Dimensional Pharmaceuticals were the first to describe a high-throughput version using a plate reader [15] and Wyeth Research published a variation of the method with SYPRO Orange instead of 1,8-ANS.

Lauryldimethylamine oxide (LDAO), also known as dodecyldimethylamine oxide (DDAO), is an amine oxide–based zwitterionic surfactant, with a C 12 (dodecyl) alkyl tail. It is one of the most frequently-used surfactants of this type. [4]
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

[1] Nucleic acid molecules are separated by applying an electric field to move the negatively charged molecules through a gel matrix of agarose , polyacrylamide , or other substances. Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel.
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 ...
Free Fire grossed $1.4 million in the United States and Canada, and $1.2 million in other territories, for a total of $2.6 million. [3] In the United States and Canada, Free Fire opened alongside The Promise, Born in China, Unforgettable and Phoenix Forgotten, and was projected to gross around $3 million from 1,070 cinemas in its opening ...
