Abstract

Axonal transport in chick embryonic retinal neurons was studied after intraocular injection of [3H]proline or [3H]fucose. Rapid transport to the contralateral optic tectum could be demonstrated from the 10th day of incubation, and the rate of rapid transport increased with age. As compared to proline-labelled proteins, a relatively larger proportion of retinal fucose-labelled glycoproteins was transported to the tectum throughout the development, with the maximal difference at 18 days. Sodium dodecyl sulphate (SDS) gel electrophoresis of leucine- or fucose-labelled tectal proteins revealed that a large number of relatively high mol. wt. polypeptides reached the optic tectum by a rapid phase of axonal transport.
