Free Amino-acids in the Hæmolymph of Calliphora erythrocephala Meigen

Article metrics

Abstract

THE recent publication by Raper and Shaw of an analysis of the amino-acids of the hæmolymph of the nymph of Aeschna cyanea1 prompts us to report a similar investigation we have carried out upon the hæmolymph of the larva of Calliphora erythrocephala. The larvæ used for this study were inbred descendants of a single female and were reared on ox liver at 25° C. for 4–5 days. The amino-acids were separated and identified by paper partition chromatography.
