Summary
By means of SDS-polyacrylamide gel electrophoresis the protein patterns of untreated, 0.5M and 1M KCl treated ribosomes of Drosophila melanogaster 4d larvae and adults are compared. 0.5M KCl treatment does not change the stage specific pattern (Fig. 1 b, c). 1 M KCl treatment removes 2 stage specific proteins from adult ribosomes (Fig. 1d, band No. 1 and 3). One protein found only in the adults is localized on the small ribosomal subunit and removed by 1 M KCl (band No. 3). The possible significance of these results is discussed.
