Induction of recA protein in Escherichia coli by three platinum (II) compounds

The Na⁺ channels of Chinese Hamster lung fibroblasts have receptor sites for tetrodotoxin, batrachotoxin, veratridine, dihydrograyanotoxin, scorpion and sea anemone toxins. The binding properties of these toxic compounds were determined and shown to be very similar to those found in a variety of excitable cells. Electrophysiological experiments indicate that these Na⁺ channels cannot be electrically activated unless previously treated by veratridine.
