Covalent labeling of protein components of the sodium channel with a photoactivable derivative of scorpion toxin.

Azidonitrobenzoyl mono[125I]iodo scorpion toxin can be covalently attached to its receptor site in electrically excitable neuroblastoma cells or synaptosomes by photolysis. A polypeptide of Mr approximately 250,000 is specifically labeled in neuroblastoma cells. Labeling is blocked by unlabeled scor...
