Drug Development Expertise Empowering Research Services for Biologics

In Vitro Assays Services


Comprehensive In Vitro Bioassays for Lead Characterization

In vitro assays play a critical role in biologics screening, developability assessment, and functional characterization. At WuXi Biologics, we offer comprehensive bioassay development services to accelerate lead selection and biologics characterization to ensure seamless CMC development.

 

Our expert in vitro team has successfully completed over 1,000 projects across monoclonal antibodies, bispecific antibodies, multispecific antibodies, antibody-drug conjugates (ADCs), fusion proteins, and cytokines. Leveraging advanced assay technologies such as cellular, biochemical, molecular, immune, and Fc effector function assays, we deliver reproducible, high-quality results with data interpretation to support biologics discovery and development.

 

Key Features of Our In Vitro Assays Services:

  • High-throughput ELISA, SPR, and FACS-based binding and competition assays for epitope mapping and protein-protein interaction studies
  • Functional cellular assays for biologics screening, such as reporter gene assays and internalization assays
  • Advanced immune assays including cytokine release profiling and cytotoxicity testing
  • Tailored solutions for bioassay development, engineered cell line development, and lead characterization
