title: The elution profile of vitamin D2 metabolites from sephadex LH20 columns.
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 believe to be 25,26-dihydroxyvitamin-D2, may yield falsely higher concentrations of apparent 24,25-dihydroxyvitamin-D3 if separation on LH20 is used.
