title: Monoclonal antibodies to rat brain alpha-adrenoceptors.
abstract: We have developed three hybridomas that produce monoclonal antibodies to rat cerebral alpha-adrenoceptors. Splenic lymphocytes from BALB/c mice immunized with unpurified digitonin-solubilized alpha-adrenoceptors were fused with the mouse myeloma line P3-x 63-Ag 8.653 to yield hybridoma cultures producing alpha-adrenoceptor monoclonal antibodies of the IgG class. However, these antibodies inhibited both alpha 1 and alpha 2 ligand binding suggesting that some molecular homology exists between alpha 1- and alpha 2-adrenoceptors in the rat brain.
