title: Purification and biochemical characterization of alpha 2-adrenergic receptor from the rat adrenocortical carcinoma.
abstract: The alpha 2-adrenergic receptor was purified from rat adrenocortical carcinoma 494 by an affinity chromatographic step using a novel para-aminoclonidine-sepharose resin followed by a gel-permeation high performance liquid chromatographic step. The iodinated receptor protein was homogeneous as evidenced by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and by high performance liquid chromatography. Both SDS-PAGE and high performance liquid chromatographic studies revealed that Mr of the protein was 64,000, suggesting the monomeric nature of the receptor protein. The purified protein showed the typical binding characteristics of alpha 2-adrenergic receptor.
