Ionic strength effects on nucleoproteins
International Journal of Biochemistry, 1978Abstract 1. 1. Homogenization of calf (Bos bovinus) thymus cells in 0.15 M triethanolamine hydrochloride (TEA-HC1) prior to the extraction of deoxyribonucleoprotein (DNP) with 0.01 M glycine results in the recovery of a fractionated DNP when compared to extracts from cells initially exposed to lower ionic strength TEA-HC1 solutions. 2. 2. The

Expression of mammalian spermatozoal nucleoproteins
Microscopy Research and Technique, 2003AbstractA dramatic remodeling of sperm chromatin occurs during mammalian spermiogenesis. Nuclear elongation and chromatin condensation are concomitant with modifications in the basic protein complement associated with DNA. A number of biochemical events accompany the displacement of histones and the appearance of protamines in elongating spermatids ...

Nucleoprotein localization by bismuth staining
Tissue and Cell, 1978Experiments on isolated mouse liver muclei involving enzyme digestion, the crosslinking of amino groups and alkaline hydrolysis demonstrate that bismuth binds to nucleoproteins through amino and phosphate groups. Analysis of the nucleoproteins extracted with salt and acid solutions in conjunction with bismuth staining after these treatments suggests ...

Nucleoprotein Layer of the Yeast Cell
Nature, 1963ELECTRON microscopy of yeast has revealed nucleic acid in a space between the cell-wall and the plasma-membrane. Fig. 1 shows: (a) the thin, double-walled, convoluted, nucleic acid-free, plasma-membrane; (b) a region (occupying almost one-tenth the total cell volume) rich in nucleic acid which lies outside the plasma-membrane directly beneath the cell ...

Zinc in Nuclear Desoxyribose Nucleoprotein
Nature, 1949SINCE 1938 I have been engaged in a general study of the distribution of zinc in normal and malignant tissues, and this work has been briefly reported from time to time1. In the early part of the work, polarographic analyses for zinc content were made on human tissues, and although some neoplasms were found to have a much higher zinc concentration ...

Virus Proteins and Nucleoproteins: An Overview
2018Genetic economy is a key feature in all aspects of viral replication. Some viruses are able to function as independently evolving entities with as few as two genes, while satellite viruses have been described that encode a single gene product. To accommodate the need for genetic economy, the viral infectious entity - the virion, generally assembles in ...
