FRACTIONATION OF HIGH AND LOW MOLECULAR WEIGHT COMPONENTS FROM WORT AND BEER BY ADSORPTION CHROMATOGRAPHY USING THE GEL SEPHADEX LH20 [PDF]
Journal of the Institute of Brewing, 1986 Column chromatography using the hydroxypropylated dextran gel Sephadex LH20 was used to fractionate the components of brewers' wort and beer. The elution profile of beer was investigated in detail and components identified. Fractions containing high molecular weight polypeptide material, small peptide material, free proline, phenylalanine, tyrosine and

The elution profile of vitamin D2 metabolites from sephadex LH20 columns.
Clinical Chemistry, 1979 Abstract A metabolite of vitamin D2 in the tissues of primates fed this vitamin co-migrates to a significant extent with 24,25-dihydroxyvitamin-D3 on columns of Sephadex LH20, with chloroform/n-hexane (60/40 by vol) as eluent. In individuals receiving vitamin D2 and in individuals with scant exposure to sunlight this metabolite, which we

Detoxification by Sephadex LH20 of Seafood Concentrates for Rotavirus Assay
Water Science and Technology, 1991 Virological analysis of seafood is often limited because of the toxic effects of the mollusc concentrates on cell cultures. We have developed a method of detoxification based on filtration through a Sephadex LH20 gel. Results show that in mussels concentrates after filtration the toxicity has decreased in a factor between 4 and 10 in 79 % of cases ...
