WebDec 5, 1982 · A genomic clone containing two tropomyosin-coding sequences has been isolated from a library of Drosophila melanogaster DNA and identified by a positive hybridization selection and an in vitro translation procedure. WebFeb 1, 2000 · ABSTRACT. Extracts of the brain/corpora cardiaca/corpora allata (Br/CC/CA) complex of Manduca sexta larvae elicit an antidiuretic effect, measured by an increase in fluid reabsorption across the cryptonephric complex of larval M. sexta. Separation of the extract by reversed-phase liquid chromatography gave two fractions with antidiuretic …
