چکیده

1. A new method has been developed for the specific extraction of histone fraction f2(a) from calfthymus deoxyribonucleoprotein at pH 7 by using a mixture of ethanol and guanidinium chloride. 2. Fraction f2(a) has been separated into the subfractions f2(a)1 and f2(a)2 by acetone precipitation from acid solution, and at pH7. 3. Modifications of existing electrophoretic methods are described that enable these fractions to be more easily characterized.

The electrophoresis of histones in polyacrylamide gel and their quantitative determination.

1. A new method has been devised for the separation of the histone fractions of calf thymus by electrophoresis in polyacrylamide gel at pH2.4. 2. The fractions have been characterized by their relative mobilities with respect to a marker protein, bovine plasma albumin. 3. A method has been developed for the quantitative determination of the separated histone fractions by measuring the colour yi...

Using selective sequential extraction techniques to evaluate tendency of soil fractions in Cd removal by Fe3O4 nanoparticles in continuous flow system

Use of nanotechnology has proven to be a promising approach toward remediation of all phases of environment. The aim of this work is to investigate the effects of different parameters on using iron III oxide nanoparticles in a continuous flow configuration for the removal of Cd2+ ionsfrom contaminated soils. Also selective sequential extraction tests are carried out to evaluate the nanoparticle...

Chromatographic 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...

N-Terminal acetyl-peptides from two calf thymus histones.

1. The same N-terminal peptide was isolated from two major calf thymus histone fractions, F2al and F2a2. 2. The structure of the peptides is N-acetylseryl-glycyl-arginine, and the yields account for most of the N-acetyl groups previously found in these histones. 3. Some other peptides not giving a ninhydrin reaction were also investigated.

Two chemically and metabolically distinct forms of calf thymus histone F3.

The F3 histones of duck erythrocytes and calf thymus have been purified and compared by a variety of techniques. The results of analytical gel electrophoresis, gel filtration, cysteine content determinations, and amino acid analysis support the conclusion that there exist two chemically and metabolically distinct forms of F3 histone. The duck erythrocyte has a single form of F3 histone, which c...
