23-25) In this case, by utilizing chaotropic conditions generated within the collected sample, human cells are selectively lysed, after which, enzyme-mediated digestion of human DNA and extracellular pathogen DNA occurs, followed by sedimentation of intact pathogen cells with the aid of centrifugation.
Rna Extraction Is Based On Lysis Using A Chaotropic Buffer Containing Guanidine Thiocynate And Using Silica As The Rna-Binding Matrix.
Briefly, specimens were digested under denaturing conditions at elevated temperatures and then lysed in the presence of chaotropic reagent.
In the following step, the lysis fluid containing DNA/RNA is transferred to a chaotropic buffer containing fresh silica beads.
In brief, the sputum samples were mixed with 2-3 volumes of the USP solution, which contained the following chemicals: 4-6 M guanidinum hydrochloride (a chaotropic agent which disrupts the hydrogen bonds), 50 mM Tris chloride (pH 7.
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.
Chaotropic acids such as guanidine hydrochloride or guanidinium thiocyanate were discovered to protect NA from nucleases because of their potent protein denaturing properties (16).
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.

Chaotropic 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).
The native state of a protein can be altered using elevated temperature, chaotropic or other chemical agents such as urea or guanidine hydrochloride, and adjustments in pH.
