Transfusion, 1981
The vasodilative effects associated with the use of sodium acetate have been reported in the literature. Preparations of plasma protein fraction (PPF) substantially free of this vasodilator were developed. This paper presents and discusses experimental work on the improved product.

Fractionation of yeast ribosomal proteins
Biochemical and Biophysical Research Communications, 1968Abstract Isolation and characterization of individual ribosomal proteins of E. coli has been reported by Traut et al. (1967). This communication is to report on the fractionation and analysis of proteins isolated from the ribosomes of brewer's yeast. It was found that, as in the case of E.

Trends in Biotechnology, 1985
Abstract The fractionation of blood plasma yields a number of therapeutic proteins which together constitute a billion dollar world-wide market. Conventional plasma fractionation procedures are being replaced by more sophisticated chromatographic techniques.

Trends in whey protein fractionation
Biotechnology Letters, 2011Whey is a by-product of cheese manufacture that is normally treated as a waste. However, it contains a mixture of proteins with important nutritional and biological attributes. To extract these valuable proteins, whey fractionation has been developed using three main techniques; namely chromatographic (e.g., ion-exchange and hydrophobic adsorption ...

Donkey’s milk protein fractions characterization
Food Chemistry, 2008Abstract Donkey’s milk may be considered a valid alternative, for infant nutrition, to powdered milks, soybean milk or other formulas, since its composition in lipids and proteins is very close to human milk. The aim of the present study is to characterize “donkey’s milk” product, especially with regard to the protein fractions.

1980
When examining the soluble protein from spinach leaves in the ultracentrifuge, Wildman and Bonner in 1947 coined the term Fraction I protein to designate a high molecular weight protein which occurred in very high yield. Subsequent studies in a number of laboratories have shown that this protein contributes up to 50% of the soluble protein of leaves ...

Fractional Brownian dynamics in proteins
The Journal of Chemical Physics, 2004Correlation functions describing relaxation processes in proteins and other complex molecular systems are known to exhibit a nonexponential decay. The simulation study presented here shows that fractional Brownian dynamics is a good model for the internal dynamics of a lysozyme molecule in solution.

Foam fractionation of globular proteins
Biotechnology and Bioengineering, 1990AbstractFoam fractionation of bovine serum albumin (BSA) was studied as a model system for potato wastewater. The effects of feed concentration, superficial gas velocity, feed flow rate, bubble size, pH, and ionic strength on the enrichment and recovery of BSA were investigated in a single‐stage continuous foam fractionation column.

Protein Fractionation At Subzero Temperatures
1978Publisher Summary The use of subzero temperatures opens a new dimension in protein fractionation both through use of mixed solvents and of a new range of temperatures weakening hydrophobic interactions. The procedure is not free from problems because the changes in solution composition and the temperature variations can modify markedly the classical ...

Fractionation of chromatin nonhistone proteins
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1973Abstract A method for the isolation and fractionation of the nonhistone proteins of chromatin is described. The method utilizes a single ion exchange column, is simple and rapid in performance and can be scaled up to preparative levels of fractionation. 91–94% of chromatin proteins are dissociated with 7 M urea, 3 M NaCl, 1 mM β-mercaptoethanol and 0.
