CHARACTERIZATION OF THE MAJOR HEMOLYMPH-PROTEINS IN CERATITIS-CAPITATA

There are four major proteins species in the haemolymph of Ceratitis capitata. Their immunological relationship to calliphorin has been shown by immunoprecipitation and Ouchterlony double diffusion test. Using SDS electrophoresis these proteins are separated into three polypeptide bands differing in molecular weight maximally by ± 2000-3000 and showing similar migration to calliphorin. From visual inspection of the stained gels it appeared that the amounts of these proteins increase from that in the three day old larvae, reaching maximal levels in the four day old larvae and white pupae and then decrease gradually throughout the pupal and early adult stages. © 1979.
