Summary

Pharmacokinetic studies of animal and human skin are often advantageously performed with low levels of C-14. We detail an efficient wet ashing method capable of detecting 20 dpm per sample, equivalent to twice the background level, thus permitting complete kinetic assays with 1 μCi or less of C-14 per subject.

Zusammenfassung

Pharmakokinetische Untersuchungen mit tierischer und menschlicher Haut werden oft vorzugsweise mit niedrigen Spiegeln von C14 durchgeführt. Wir stellen eine effiziente Feucht-Veraschungsmethode vor, die erlaubt, 20 dpm pro Ansatz zu erfassen, was dem doppelten Basiswert entspricht. So können vollständige Untersuchungen mit 1 μCi oder weniger von C14 pro Versuchsobjekt durchgeführt werden.
