[Preparation and characteristics of monoclonal antibodies against GTP-binding protein from the bovine retina].
Five monoclonal antibodies against the native GTP-binding protein (transducin) from bovine retina have been prepared. By immunoblotting and immunoenzymatic analysis of the isolated alpha- and gamma-subunits of transducin and the beta gamma-subunit complex it was determined that two monoclonal antibodies A3G7 and A3C10 recognize linear antigenic determinants on the alpha-subunit, two other, A3E4 and 3B3, bound specifically to the gamma-subunit, and monoclonal antibodies 1C3 interact only with native transducin. Both antibodies against the alpha-subunit inhibited transducin GTPase activity, whereas antibodies A3E4, 3B3 and 1C3 did not affect it.
