EMD Millipore, the Life Science division of Merck KGaA, Darmstadt, Germany, launched Cellvento CHO-200 chemically defined cell culture medium, a product of non-animal origin that delivers robust cell growth. Accompanied by complementary Cellvento Feed products, the new medium is optimized specifically for fed-batch processes using CHO-S cell types expressing monoclonal antibodies. Cellvento CHO-200 medium and its corresponding feeds do not contain hydrolysates or components of unknown composition, resulting in very good lot-to-lot consistency. The formulation supports high cell density growth and extended culture duration as well as long duration of high cell viability. Cellvento CHO-200 medium and Cellvento Feeds are produced in dry powder form at the company’s cGMP facility, using fully traceable raw materials sourced from qualified suppliers, leading to reliable homogeneity that allows for effective powder dissolution and uniform component distribution. A liquid version of Cellvento CHO-200 medium will be introduced in the fall of 2013.
