Methods are described for the fluorometric determination of plasma adenosine concentrations, using HPLC. Plasma obtained from blood of dogs treated with erythro-(2-hydroxy-3-nonyl)adenine hydrochloride and dipyridamole was deproteinized with perchloric acid and the neutralized sample was put sequent

Reaction of a mixture of ethanolamine and boric acid with reducing sugars gave intense fluorescence. Application of this reaction to the postcolumn derivatization in high-performance liquid chromatography provided a rapid, sensitive, and simple detection and determination of carbohydrates under a mi
## Abstract An assay for the measurement of unbound L‐tryptophan concentrations in plasma was developed using reverse‐phase HPLC with fluorescence detection. Unbound L‐tryptophan from plasma was obtained using the Amicon MPS‐1 ultrafiltration device. L‐tryptophan binding to the membrane in the ultr
