GenScript has developed the proprietary TurboCHO™ expression system for higher-titer production of recombinant antibodies, compared to our previous HD transient expression. Unlike TurboCHO™ High Throughput platform, TurboCHO™ Express is designed for middle-scale production, and the overall timeline from gene synthesis to antibody delivery is only 3 weeks! In addition, multiple purification and endotoxin control options are included in the default QC list, ensuring high-quality product delivery. TurboCHO™ Express platform can also deliver a range of purified antibody products (e.g., IgGs, Fab, scFV, VHH, bi-specific antibodies, and more) in quantities (i.e., from 5 mg to 500 mg).
