153Gadolinium as a useful radiolanthanide for long-term labeling of tissues in Japanese quail.

Abstract

153Gadolinium (153Gd), with gamma energies of 97 keV (30%) and 103 keV (20%), and a nuclear-life of 242 days and with no primary charged particles, was selected as the radiolanthanide for labeling proteins and tissues in Japanese quail. Ranges of dose-responses 18 hr after giving Gd (153Gd labeled) were: males, livers 24.4% for .00015 mumol/100 g to 63.8… (More)
