For complex diseases in which multiple mediators contribute to overall disease pathogenesis by distinct or redundant mechanisms, simultaneous blockade of multiple targets may yield better therapeutic efficacy than inhibition of a single target. However, developing two separate monoclonal antibodies for clinical use as combination therapy is impractical,(More)
We describe a novel polyprotein precursor-based approach to express antibodies from mammalian cells. Rather than expressing heavy and light chain proteins from separate expression units, the antibody heavy and light chains are contained in one single-open reading frame (sORF) separated by an intein gene fused in frame. Inside mammalian cells this ORF is(More)
Efficient production of large quantities of therapeutic antibodies is becoming a major goal of the pharmaceutical industry. We developed a proprietary expression system using a polyprotein precursor-based approach to antibody expression in mammalian cells. In this approach, the coding regions for heavy and light chains are included within a single open(More)
Recombinant therapeutic monoclonal antibodies exhibit a high degree of heterogeneity that can arise from various post-translational modifications. The formulation for a protein product is to maintain a specific pH and to minimize further modifications. Generally Recognized as Safe (GRAS), citric acid is commonly used for formulation to maintain a pH at a(More)
