In vitro efficacy of an antibody-drug conjugate (ADC) is an important parameter in ADC development projects. It is the first qualitative evaluation of the drug efficacy of an ADC and it provides a baseline for ADC improvement and a guideline for downstream process designs. Using our advanced analytical platform, Creative biolabs provides our global clients with comprehensive ADC in vitro cytotoxicity analyses via the evaluation of cell viability, cell apoptosis, cell cycle status... using our large collection of tumor cell lines.
