Abstract:
A monoclonal antibody recognizing the alpha 2 delta complex of the dihydropyridine (DHP)-sensitive calcium channel of skeletal muscle immunoprecipitated most of the DHP receptor solubilized from bovine and rabbit brains, and bovine cardiac muscle. However, it did not significantly immunoprecipitate the high affinity omega-conotoxin receptor solubilized from these brains. These results indicate that the DHP receptor and the high affinity omega-conotoxin receptor are different molecules in mammalian brain.
