Advances in Label-Free Assays for Antibody Discovery, Development, Characterization and Bioprocessing Webinar

Date: Dec. 1, 2010

Label-free assays provide labor-efficient methods for analysis of proteins and peptides during drug development. An established label-free technology, Biolayer Interferometry (BLI), works by continuously monitoring ligand binding on the tip of an optical biosensor, thereby eliminating the need for protein labeling with fluorescent or chromogenic tags.
This method provides multichannel processing of samples using dip and read biosensors, accommodates 96- and 384-well assay formats, simplifies real-time quantitation and kinetic characterization (real-time ka, kd, and affinity) of multiple ligand-ligand interactions, provides crude sample compatibility, and reduces handling steps over traditional technologies such as ELISA, HPLC, and SPR.  Biolayer Interferometry assays have yielded comparable or better resolution and sensitivity to existing bioassay methods and are highly adaptable to analysis of multiple types of biomolecules.
The BLI label-free assays detect low affinity binders often missed by ELISA. Since BLI does not involve microfluidics, these label-free assays allow offline batch immobilization of ligands onto trays of biosensor tips, further streamlining and enabling assay workflows not previously possible.
In this webinar, you will learn how label-free assays embodied in the OCTET platform have been used to optimize therapeutic antibody production and characterization and streamline producer strain identification as well as for the high-throughput analysis of antibody-antigen or protein-protein interactions and, combined with robotics, for unattended analysis of large sets of biotherapeutic candidates.
