    Case Study
    Eliminating BsAb Precipitation through Custom Antibody Design & Engineering

     

    Using in silico analysis and in vitro testing, conformational instability of antibody B was identified as a key driver of bsAb aggregation. After tailored antibody engineering, the optimized bsAb showed no detectable precipitation in high concentrations. .

     

    Case Study
    LC-MS-Guided Purification for Common Light-Chain (LC) Bispecific Antibody Production

     

    In this case study, a common LC bsAb was produced using LC-MS-assisted purification. Following affinity purification, mixed mode, and CEX polishing, half antibodies and homodimers were effectively removed, resulting in final bsAb product with 98.4% purity.
