1. A tentative method is described for extracting a labile nucleo-protein from scarlatinal Streptococcus hemolyticus. 2. The product differs chemically and serologically from the fractions prepared by subsequent alkaline extraction of the cell residues, and from protein obtained by the classical method for extraction of bacterial "nucleoproteins." 3. The new nucleoprotein is sensitive to very w...
In the early stages of liver Carcinogenesis induced by 4-dimethylaminoazobenzene the subcellular pattern of calcium, magnesium, sodium, and potassium is sharply altered. Divalent cations decrease in the nuclear and mitochondrial fractions and in crease in the residual fraction. In the case of mitochondria, however, cations decrease proportionally to the amount of proteins and nucleoproteins in ...
Immunofluorescence microscopy of the skin has disclosed antibodies bound to epidermal cell nuclei in several connective tissue disorders. To establish the diagnostic potential of this phenomenon the results of immunofluorescence microscopy of biopsy specimens from 1651 subjects with various diseases and from 315 patients with systemic connective tissue disorders and related diseases were review...
Human sperm nucleoproteins consist of protamines and histones. Changes in composition of these proteins are thought to correlate with spermatogenesis and may be involved in some instances of male infertility. We sought to separate sperm nucleoproteins including variants of protamine using an improved two-dimensional electrophoretic method, with the aim of comprehensively analysing all sperm nuc...
More than 20 years have passed since the discovery of natural covalent complexes of nucleic acids and proteins (1–5). Covalent complexes of nucleic acids and proteins are both stable and highly specific because they are nucleoproteins linked by a unique covalent bond. Two important properties are associated with these complexes: (i) a novel structure, describing a new class of natural nucleopro...
We tested blood samples from domestic and captive farmed animals in Minnesota, USA, to determine exposure to severe fever with thrombocytopenia syndrome virus and Heartland-like virus. We found antibodies against virus nucleoproteins in 10%-18% of samples from cattle, sheep, goats, deer, and elk in 24 Minnesota counties.
