Photoincorporation of ligands into the benzodiazepine site of native gamma-aminobutyric acidA (GABAA) receptors provides useful information about the nature of the benzodiazepine (BZ) binding site. Photoincorporation of flunitrazepam into a single population of GABAA receptors, recombinant human alpha1beta3gamma2, was investigated
