The bioactivity of mAbs is often confirmed by rigorous efficacy and potency testing. This is an essential part of the antibody drug evaluation system, which plays an important role in determining the mechanism of action (MOA) of drugs, and provides a foundation for preparing investigational new drug (IND) applications.

Owing to the importance of in vitro screening and target validation during the early stages of antibody discovery, Sino Biological has established in vitro activity assay platforms to streamline antibody drug development projects. To fulfill diverse testing needs, Sino Biological provides various reagents and extensive in vitro efficacy evaluation services, including target proteins, protein antigen expression services, control antibody production service, cytokines, ELISA kit development service, cell line development service, negative controls, and GFPSpark® expression vectors.
