  • Title: Effects of detergent on the binding of solubilized sodium channels to immobilized wheat germ agglutinin: structural implications.
    Author: Weiner JS, Rudy B.
    Journal: Biochim Biophys Acta; 1988 Oct 20; 944(3):521-6. PubMed ID: 2846065.
    Abstract:
    The binding of the solubilized voltage-dependent sodium channel from rat brain to immobilized wheat germ agglutinin (WGA) is detergent-dependent. When solubilized in sodium cholate, only 11% of total recovered channels bound to a WGA-Sepharose column. When solubilized in Triton X-100 or CHAPS, however, 80% and 60% could bind, respectively. The effect of cholate on sodium channel binding is relatively specific: the major rat brain glycoproteins which bind to immobilized WGA are roughly the same in either Triton or cholate, as analyzed by SDS gel electrophoresis. The structural implications for the channel are discussed.
