• Recombinant Protein Expression and Manufacturing

    Posted on Dec 27, 2018

    Recombinant proteins are expressed in bacteria, yeast, mammalian or in the baculovirus system. The gene of interest is transfected into the appropriate host together with regulatory elements that allow very high levels of production. Protein production may be intracellular, or may accumulate in the bacterial periplasmic space, or be secreted into the medium of cells.
    The scale may be a few mL for analytical purposes, or in batches of up to 20 L in bacterial or yeast fermentation, or up to 50 L in mammalian suspension, porous bead cultures.
