title: Fluorometric assay of B6 vitamers in biological material.
abstract: A method for the separation and assay of all B6 vitamers from a single sample of serum is reported. A new reagent system containing sodium glyoxalate, potassium aluminum, sulfate and manganese dioxide was used for quantitative conversion of pyridoxamine and its phosphate to the corresponding aldehydes by a combination of transamination and oxidation reactions.
