title: Developmental properties of the fast Na+ channel in embryonic cardiac cells using neurotoxins.
abstract: This paper describes how neurotoxins specific of the fast Na+ channel are used to study its differentiation in embryonic cardiac cells during heart ontogenesis. Structural and functional differentiation of the fast Na+ channel have been followed using both electrophysiological and biochemical techniques.
