DEVELOPMENTAL CHANGES IN THE LATE LARVA OF CALLIPHORA STYGIA III. THE OCCURRENCE AND SYNTHESIS OF SPECIFIC TISSUE PROTEINS

Abstract

The occurrence and synthesis of soluble proteins from certain larval tissues of O. 8tygia have been examined by acrylamide.gel electrophoresis and autoradio-graphy at the feeding (days 4-6), wandering (days 7-10), and quiescent (day 11) stages of third-instar development. The protein species investigated are distributed as follows: fat body, 22; plasma, 21; body wall, 18; salivary gland cells, 16; salivary secretion, 18.
