Abstract
The stage-specific appearance of calliphorin in cuticles of Calliphora vicina was analysed by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotting. The fate of the protein, injected into last instar larvae, was pursued by autoradiography of histological sections. Fractionation of sclerotized pupal cuticle in buffer-soluble, urea-soluble and NaOH-soluble fractions shows that calliphorin forms covalent and non-covalent links with other cuticle components. Calliphorin traverses the epidermal cells and enters the cuticle in an undegraded state and appears to be an important constituent of the sclerotizing system.Entities:
