The development of a novel assay to calculate the kinetic binding parameters of up to 30 antibodies simultaneously to living cells.
Characterizing the properties controlling an antibody-receptor interaction—such as the kinetic rate constants and affinity—is a critical step during drug discovery. Cell-based methods can be used due to their physiological relevance. However, current assays may require long incubation times, lack kinetic information and require labeling. We developed a label-free assay to determine ka, kd and KD of up to 30 antibodies on live cells. This method is amenable to human IgG or rabbit IgG antibodies and all cell types. Finally, we will discuss the advantages of implementing this method at early stages of the screening cascade.
What will you learn?
- Limitations of current pre-equilibrium methods to determine kinetic rate constants of antibody-receptor interactions on cells
- Details of a novel method to determine kinetic rate constants of unlabeled antibodies to cells
- How an automated microfluidic method can accelerate selection of lead candidates for preclinical studies
Who this may interest?
- Bioanalytical scientists and drug development scientists involved in the development of monoclonal antibody-based therapeutics
- Group leaders or Director-level scientists responsible for workflow, productivity and efficiencies
