The distribution of specific binding of the 5-HT3 receptor ligand [3H]GR65630 in rat brain using quantitative autoradiography.

We have examined the distribution of specific binding of the 5-HT3 receptor ligand [3H]GR65630 to rat brain using quantitative autoradiography. Brain tissue was frozen and thin sections (20 microns) cut. Slide-mounted tissue sections were incubated with [3H]GR65630 (0.2 nM) in the presence or absence of metoclopramide (30 microM, to define non-specific… CONTINUE READING
