Large-Scale Freezing of Biologics

    Production of biologics is expensive. To optimize capacity use, bulk protein solution produced in manufacturing campaigns is often converted into drug product based on market demand, so it may be stored for relatively long periods. To decouple production of bulk solution from that of a final drug product, the bulk is often stored frozen. Transport of frozen bulk between sites offers several practical advantages over bulk transport in the liquid state (2–8 °C). Maintaining 2–8 °C requires accurate…
