Chromatographic fractionation of deoxyribonucleic acids.
The investigation of the chemistry of genetics is facilitated by the availability of homogeneous preparations of deoxyribonucleic acid (DNA). For example, the DNA of T-even bacteriophages, which contain a single molecule of DNA per infectious particle (3), can be extracted as molecules of uniform length (4) and composition (5). Chemical and biological studies of the DNA’s of higher organisms, h...
متن کاملDetermination of the hydroxy and carboxylic acid groups in natural complex mixtures of hydroxy fatty acids by 1H nuclear magnetic resonance spectroscopy.
The use of trichloroacetyl isocyanate (TAI) to mark both hydroxyl and carboxyl groups borne by the hydrolysis or methanolysis of suberin fragments (a complex mixture of hydroxy fatty acids), allowed the quantitative assessment of the ratio between carboxyl and hydroxy groups, as well as the ratio between primary and secondary hydroxy groups, to be carried out reliably by 1H nuclear magnetic res...
متن کاملPhotodiode array detection for liquid chromatographic profiling of carboxylic acids in physiological fluids: 3-hydroxy-3-methylglutaric aciduria.
3-Hydroxy-3-methylglutaric aciduria was detected in a newborn. The progress of the dietary therapy for the disorder was monitored by dual-column "high-performance" liquid chromatography with a computer-controlled photodiode array spectrophotometric detector. This procedure is a quick way to detect and monitor the progress of 3-hydroxy-3-methylglutaric aciduria.
متن کاملChromatographic fractionation of phosvitin.
The presence of phosphorus-containing protein in the yolk of the hen egg was already recognized in 1900 (1). Since then, the egg yolk phosphoproteins received attention in several laboratories (cf. (2)). The first detailed study of the most highly phosphorylated fraction of yolk phosphoprotein, phosvitin, was reported by Mecham and Olcott (3) in 1949. They isolated a product containing 10% phos...
متن کاملThe Liquid Density of Complex Liquid Mixtures
A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from Ttp to T<su...
