Antisera were raised against purified subunits of regulatory GTP-binding proteins (G proteins) and against synthetic peptides that correspond to defined regions of G proteins. Peptide antisera were generated that recognized all α or all β subunits from G(s), G(i), G(o), and transducin; others recognized only G(sα) or G(oα). Such cross-reaction or complete specificity for a given α subunit was not obtained when purified subunits were injected. Peptide antisera were used to identify G protein subunits in selected tissue membrane preparations by immunoblots.
