Abstract

1. 1. Lipophorin was isolated from the haemolymph of adult tsetse fly, Glossina morsitans morsitans, by ultracentrifugation in a potassium bromide density gradient. 2. 2. The tsetse fly lipophorin (Mr {reversed tilde equals} 600,000) has a density of {reversed tilde equals} 1.11 g/ml and consists of two apoproteins, apolipophorin-I (apoLp-I, Mr {reversed tilde equals} 250,000) and apolipophorin-II (apoLp-II, Mr {reversed tilde equals} 80,000), both of which are glycosylated as shown by staining with periodate-Schiff reagent. The protein complex is composed of 49% protein and 51% lipids. 3. 3. The finding of lipophorin in tsetse fly haemolymph suggests that, although these flies primarily utilize proline for their energy needs, there is an active transport mechanism for the supply of lipid requirement. © 1991.
