E Coli

Recombinant proteins from Escherichia coli are used in research because this bacterium grows fast, is easy to handle, and produces proteins such as interleukins in large amounts. Scientists rely on E. coli expression for antibodies, cytokines, and other proteins needed in immunology, cancer, and infectious disease studies. Data from NIH and NCBI publications confirm that E. coli remains one of the most efficient and reliable hosts for protein production.
