Abstract
|
|
|
|
Changes and possible origin of haemolymph proteins during the cuticle formation and hardening are determined by means of acrylamide gel electrophoresis and immunodiffusion. The results by acrylamide gel electrophoresis showed at least 19 protein bands in the haemolymph and 13 fractions in the fat body with relatively constant pattern during the period of cuticle formation and hardening. Both haemolymph and fat body proteins are generally characterized by the presence of three to four heavy stained bands and several thin bands near the top region of the gel. At least over five haemolymph proteins are constantly present during this period. Immunodiffusion tests show that of total eight to nine pupal haemolymph proteins two proteins were already detected in the fat body before pupation and other two proteins were also found in the fat body immediately after pupation, suggesting fat body as possible source of these two haemolymph proteins.
