Analytical biochemistry, 210(2), 337-343 (1993-05-01)
RNA isolated by conventional guanidinium isothiocyanate methods from tissues of a mollusc (red abalone: Haliotis rufescens) is largely degraded and discolored by contaminants. These contaminants are associated with inhibition of reverse transcriptase, prevent accurate spectrophotometric determination of RNA concentration, and

A new method of total RNA isolation by a single extraction with an acid guanidinium thiocyanate-phenol-chloroform mixture is described. The method provides a pure preparation of undegraded RNA in high yield and can be completed within 4 h. It is

Neutron diffraction experiments and molecular dynamics simulations are used to study the structure of aqueous solutions of two electrolytes: guanidinium sulfate (a mild protein conformation stabilizer) and guanidinium thiocyanate (a powerful denaturant). The MD simulations find the unexpected result that
