Abstract
Cationic ferritin bound in a time and concentration dependent manner to all surfaces of [chick embryo] ciliary ganglion neurons in culture except mounds and veils. In chase experiments, bound ferritin cleared from the cell surfaces and formed larger and larger patches, even at low temperatures. Binding of cationic ferritin was inhibited by poly-L-lysine, potentiated by poly-L-glutamate and not affected by neuraminidase (acylneuraminyl hydrolase, EC 3.2.1.18), hyaluronidase (hyaluronoglucosidase, hyaluronate 4-glycanhydrolase, EC 3.2.1.35) or chondroitin ABC lyase (EC 4.2.2.4).
