Axonal transport of tritium-labeled putrescinein the embryonic visual system of zebrafish.
The transport of [(3)H]putrescine is demonstrated by autoradiography in the retino-tectal tract of Brachydanio rerio embryos. Transport of [(3)H]putrescine appears to be more rapid than that of tritium-labeled protein and is not inhibited by a colchicine effect on axonal neurotubules as is protein transport. The radioactivity transported to the brain is found, on electrophoresis, in the putrescine fraction.
