Despite being less soluble in water than guanidine hydrochloride, another common salt of guanidine, GuSCN has stronger denaturing properties because both its ions are chaotropic
All NA will bind to silica surfaces under specific binding conditions, especially in the presence of chaotropic
Given our observed inability to greatly alter soy flour adhesion using chaotropic
agents, salts, surfactants, or co-solvents (Frihart and Lorenz 2013), which is in contrast to the literature observations with soy protein isolate (Sun 2005b), we concluded that the carbohydrates were suppressing protein alteration for improved adhesion.
RNA Extraction: It was performed as per the method followed by Ken et al.(2012)5 briefly 200l of each sample (nasopharyngeal aspirates or throat swabs) was added to 400l lysis/binding buffer containing a chaotropic
salt poly(A) and proteinase K and then incubated for 45 minutes.

The concepts of kosmotropic and chaotropic
solutes (water structure makers and breakers), introduced by Collins and Washabaugh in 1985, have been used extensively by the biochemical and biophysical communities .
Also, desorption usually involves usage of a solution containing chaotropic
agents or detergents, which leads to complexity in subsequent processing steps and also adds to environmental burden.

Avidity of patient samples used for isolation of anti-[beta]2GPI was determined using a chaotropic
variant of the in-house anti-[beta]2GPI ELISA.
anions favour the formation of complex more than kosmotropic anions this is because chaotropes have low surface tension values as compared to kosmotropes which lead to strengthening of hydrophobic interaction and enhances the complex formation which in turn shift the LCST toward lower temperature.
Kosmotropic (Glycerol) and chaotropic
(NaCl) salt ions are mostly used to create water stress which either disrupt or enhance hydrogen bonding networks (Collins & Washabaugh, 1985; Cacace, Landau & Ramsden, 1997).
