title: The type I and type II gamma-aminobutyric acid/benzodiazepine receptor: 1. Purification and two-dimensional electrophoretic analysis of the receptor from cortex and cerebellum.
abstract: The gamma-aminobutyric acid/benzodiazepine receptor complex was purified from rat cortex and cerebellum by benzodiazepine affinity chromatography. Receptors purified from cortex and cerebellum showed different relative affinities for Cl 218872, a non-benzodiazepine ligand which discriminates type I and type II receptors. In contrast, no differences in subunit composition could be detected between these two purified receptor preparations when analyzed by two-dimensional gel electrophoresis.
