Incubation o f deproteinized larval cuticle (chitin flakes) with purified arylphorin (calliphorin) or larval haemolymph o f Calliphora vicina resulted in the formation o f a chitin-protein complex. Enzymatic oxidation o f N-ß-alanyldopamine (N D A B ) in the presence o f chitin flakes or the chitin-protein complex, resulted in various degrees o f cross-linking o f N BA D quinone formed with chi...
