title: In vivo distributions of some component fractions of Tc(NaBH4)-HEDP mixtures separated by anion exchange high performance liquid chromatography.
abstract: Anion exchange high performance liquid chromatography has been utilized to separate the component Tc-HEDP complexes of "carrier added" as well as "no carrier added" 99mTc(NaBH4)-HEDP reaction mixtures. The chromatographically separated "carrier added" Tc-HEDP components exhibit distinctly different biodistributions which are directly related to the chromatographic characteristics of the individual components. The Tc-HEDP complexes with shortest retention times, and therefore the lowest negative "charge density" have the maximum uptake on the bone, minimum uptake in the kidney, and fastest blood clearance.
