salting-out procedure
DNA from archival Papanicolaou stained and unstained cytological smears was successfully isolated using a simple, rapid and inexpensive salting-out procedure. The quality of DNA was controlled by polymerase chain reaction (PCR) amplification of segments of the human P-globin, human P-actin and human papillomavirus LI genes. Only negligible differences in amplification efficiency were observed b...
متن کاملHigh-performance liquid chromatography of coproporphyrin isomers.
A reversed-phase system is described for the simultaneous isocratic separation of coproporphyrin I, II, III and IV isomers. The retention behaviour of coproporphyrin I and III is studied in detail. The method is suitable for both analytical and semi-preparative separation.

Phase segregation in aqueous biphasic systems (ABS) composed of four hydrophilic ionic liquids (ILs): 1-butyl-3-methylimidazolium methylsulfate and 1-ethyl-3-methylimidazolium methylsulfate (C(n)C₁im C₁SO₄, n = 2 and 4), tributylmethyl phosphonium methylsulfate (P₄₄₄₁ C₁SO₄) and methylpyridinium methylsulfate (C₁Py C₁SO₄) and two high charge density potassium inorganic salts (K₂CO₃ and K₂HPO₄) ...
متن کامل1H NMR and molecular dynamics evidence for an unexpected interaction on the origin of salting-in/salting-out phenomena.
By employing (1)H NMR spectroscopy and molecular simulations, we provide an explanation for recent observations that the aqueous solubilities of ionic liquids exhibit salting-out to salting-in regimes upon addition of distinct inorganic salt ions. Using a typical ionic liquid [1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide], we observed the existence of preferential specific inte...
متن کاملSalting-in with a salting-out agent: explaining the cation specific effects on the aqueous solubility of amino acids.
Although the understanding of ion specific effects on the aqueous solubilities of biomolecules is crucial for the development of many areas of biochemistry and life sciences, a consensual and well-supported molecular picture of the phenomena has not yet been established. Mostly, the influence of cations and the nature of the molecular interactions responsible for the reversal of the Hofmeister ...
