Isolation and Determination of Polymeric Polyphenols in Wines Using Sephadex LH-20
American Journal of Enology and Viticulture, 1991Chromatography on Sephadex LH-20 separated non-polymeric and polymeric phenols in wines. Concentrations of polymeric phenols in white wines made with five-day pomace contact were directly related to polymeric phenol concentrations in skin tissues ...

Chromatography of Na125I on Sephadex gels
Journal of Chromatography A, 1976Abstract Elution volumes of NaI and Na 125 I appear to differ significantly when chromatographed on Sephadex G-15 or G-10. Using distilled water as the eluent, radioiodide was eluted in the void volume of the column while NaI was found eluted after NaCl.

Analytical Biochemistry, 1984
A simple procedure for the large scale purification of unactivated human factor VII is described. The initial steps, common to prior purification methods, include adsorption onto barium citrate, ammonium sulfate fractionation, and DEAE-Sephadex chromatography.

[30] Separation of carotenoids on lipophilic sephadex
1980Publisher Summary This chapter discusses the separation of carotenoids on lipophilic Sephadex. For the study of biogenesis of carotenoids using radioisotopes in vivo , it is necessary to remove steroids from carotenoids. Because both the groups have a common precursor, mevalonic acid, the radioactivity incorporated into steroids may interfere with ...

Sorption Effects in Gel Filtration: I. A Survey of Amino Acid Behavior on Sephadex G-10
, 1967Sephadex G-10, as supplied by the manufacturer, behaves as a weak cation exchanger. The cation-exchange capacity can be nearly eliminated by washing the gel with 1 M aqueous pyridine. The behavior of amino acids and other small solutes on pyridine-washed

Effects of filtration of semen doses from subfertile boars through neuter Sephadex columns.
Reproduction in domestic animals = Zuchthygiene, 2007This study was designed to develop a method of improving the quality of sperm obtained from subfertile Piétrain boars. Seminal doses were filtered through neuter Sephadex columns (G-25 Medium, G-50 Fine, G-50 Medium and G-75, length 10 +/- 0.5 cm, flow ...

The separation of ribonucleic acids on sephadex columns
Journal of Chromatography A, 1968Abstract A method was developed for the chromatographic separation of soluble ribonucleic acid (sRNA) and ribosomal ribonucleic acid (rRNA). It involves the use of Sephadex G-75, which was equilibrated with 1.5 M NaCl and 0.5 M Tris buffer, pH 7.5. After the mixture was embedded, the column was eluted with 0.5 M Tris buffer using a 50 ml mixing

N.M.R. studies of water proton relaxation in Sephadex bead suspensions
, 1989The effects of morphology and diffusive exchange on N.M.R. water proton transverse relaxation times in a model heterogeneous system consisting of packed Sephadex beads are interpreted within a unified theoretical framework based on the Bloch-Torrey ...

Adsorption chromatography of phenylalanine peptides on Sephadex
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1968The adsorption properties of dextran gels have been utilized to separate the first six members of an homologous series of phenylalanine peptides, the longer members being more highly retarded. Separation is influenced by gel structure, pH and the ionic environment.
