Chromatographic 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 کاملChromatographic 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 کاملChromatographic fractionation of calf thymus histone.
Evidence has recently accumulated that histone preparations, particularly those derived from the nuclei of calf thymus, may contain a mixture of different basic proteins. Variations in the amino acid composition of histone fractions extracted and precipitated by different means have been demonstrated by Stedman and Stedman (2), Daly, Mirsky, and Ris (3), Eadie and Leaf (4), Hamer (5), Davison a...
متن کاملChromatographic Fractionation of Myelin Basic Protein
Guinea pig myelin basic protein has been chromatographed on carboxymethylcellulose at alkaline pH to yield five purified components, each of which was shown to be identical with one of the several components which have previously been observed electrophoretically at alkaline pH. Each purified chromatographic component was stable upon electrophoresis at alkaline pH. No differences in molecular s...
متن کاملChromatographic fractionation of acetic acid-solubilized rat tail tendon collagen.
It has been known since before 1870 (1) that collagen swells in dilute acetic acid, loses its fibrillar appearance, and eventually dissolves, in part, to yield a viscous solution. If the temperature of this solution is raised steadily, its viscosity decreases, at first slightly, then sharply, a phenomenon which occurs between 13” and 40”, depending on the type of collagen (2). Physical measurem...
