The construction of an antibody-drug conjugate (ADC) is the covalent coupling of a monoclonal antibody and a toxic payload drug via a linker molecule. The ultimate goal for an ADC development project is to deploy the resulted ADC into in vivo systems, both in model animals and eventually human patients, to cure cancer and other diseases utilizing its payload efficacy. However, prior to in vivo deployment, information regarding basic biochemical characteristics and in vitro efficacy must be acquired for a proper evaluation of the ADC to determine the proceedings and directions of the project. Creative Biolabs offers a comprehensive set of ADC in vitro analysis services to assist our clients determine the biochemistry and in vitro efficacy of an ADC and provide a guideline for project progression.
