Uptake of foreign ferritin in platy, Xiphophorus maculatus (Poeciliidae: Teleostei) [PDF]

open access: yesDiseases of Aquatic Organisms, 2002
The ability and capacity of various tissues in platy Xiphophorus maculatus L. to take up horse-spleen ferritin injected into the blood stream are described. Ferritin was injected intraperioneally, and the cellular uptake was demonstrated as Prussian blue precipitations in tissues treated with acid ferrocyanide solutions.
