Performance, Flexibility and Confidence for Real-Time Label-Free, High-Sensitivity Binding Analytical Service on Octet® BLI Platform

Successful IND submission and market authorization must rely on efficient combination of drug discovery and preclinical processess.

The development of drugs is an expensive and lengthy process. During discovery and preclinical phases, researches must screen and select multiple hit and lead candidates, optimize functional and biophysical properties, investigate developability and define optimal conditions for production and manufacturing. Implementing binding assay in the early stages of drug discovery can decrease downstream failure rates and prevent unnecessary spending of time and resources.

IgG Drug Discovery and Preclinical Workflow

BLI can support diverse molecular binding applications ranging from library screening assays (e.g Koff ranking, functional screening), drug lead candidate selection and characterization (e.g kinetic & affinity measurement, epitope binning), structure-activity relationship studies (e.g epitope mapping…), cell line development (CLD) monitoring during biologic production process, and optimization and surveillance of bioprocess during developability studies and development phases (EC50 dose response).

Besides applications with regard to therapeutic discovery and development, the versatility of BLI can be used to monitor target expression processes optimization and validate protein functionality thoughout production, purification and formulation steps. Consequently, whether soluble target or embedded target (e.g liposome, VLP, viral vector, nanodisc…), kinetic analysis with binding partners and quantitation assays during production steps can be perfomed to control the bioproducts quality.
