Immunological evidence for structural homology between Drosophila melanogaster (S14), rabbit liver (S12), Saccharomyces cerevisiae (S25), Bacillus subtilis (S6), and Escherichia coli (S6) ribosomal proteins.

Specific antibodies directed against Drosophila melanogaster acidic ribosomal protein S14 were used in a comparative study of eucaryotic and procaryotic ribosomes by immunoblotting and enzyme-linked immunosorbent assays. Common antigenic determinants and, thus, structural homology were found between D. melanogaster, Saccharomyces cerevisiae (S25), rabbit liver (S12), Bacillus subtilis (S6), and Escherichia coli (S6) ribosomes.
