Biochemists and other biomedical researchers depend on one another for substances and preparations they used in their experiments. Cohn here mentioned that he was supplying Heidelberger with B-galactosidase, an enzyme that helps bacteria ferment sugar and that played a key role in bacterial genetics research in the 1950s. Cohn also mentioned the use of radioactive tags to identify individual proteins in solutions.
