| Abstract: |  Specific binding of [3H]muscimol (11.5 nM), related to GABA receptors, occurred in subcellular particles prepared from 4-, 8-, and 12-day cultures of embryonic (14-to 15-day-old) mouse cerebrum, but not to particles prepared from 20-to 45-day cultures. Phase-contrast microscopy revealed that the presence of neuronal elements (neuroblasts, neurites) paralleled the binding of [3H]muscimol. Further evidence is thus provided for using high-affinity [3H]muscimol binding as a neuronal marker.Supported by a UNESCO/IBRO fellowship |
