Immunoelectrophoretic characterization of the ADP/ATP carrier from heart, kidney, and liver.
Earlier studies gave an indication for an organ specificity of the ADP/ATP carrier. We used a modified charge-shift crossed immunoelectrophoresis for a more precise immunochemical characterization of this detergent-solubilized hydrophobic membrane protein. Immunological differences between the carrier protein from heart, kidney, and liver were demonstrated by a different electrophoretic migration of the three ligand-protein complexes in the first dimension and a distinct staining intensity, sharpness, and shape of the precipitates in the second dimension. However, the antibodies against the heart and kidney protein showed a cross-reactivity between the three antigens. The results are consistent with the view that the ADP/ATP carrier has organ-specific antigenic determinants although there is a partial identity between the carrier proteins from heart, kidney, and liver.
