The antibody binding assay evaluates the binding between antibody-based drugs and target-positive cells, target-humanized mouse cells, or target-modified mouse cells. It determines the EC50 of the drug and provides a reference for in vivo efficacy by comparing it with positive control drugs.
Experimental Case Study: Analyzing the binding activity of target-modified cells with different concentrations of Opdivo and Keytruda.

Advantages
- Familiar with the regulatory requirements for new drug submissions. 
- Extensive repository of target cells (150+ CDX cell lines and humanized engineered mice cell lines). 
- Provision of common target-positive antibody drugs as controls for free.
