Axonal transport and the movement of 45Ca inside the giant axon of squid.
45Ca was microinjected directly into the giant axon of squid, and the radioisotope profile along the axon was determined after 2-12 h. Our results indicated that the intracellular Ca ions at the axon, unlike those at the cell body, were not axonally transported at a fast rate. The implication of this finding on the involvement of Ca in the axonal transport system is discussed.
