Kinetic Analysis of Monoclonal Antibody Binding to HIV-1 gp120-derived Hyperglycosylated Cores

Abstract

Kinetic analysis of antibodies is one of the important studies for characterization of antibodies and screening of ligands. In our recent study (Ingale et al., 2014), we compared the antigenic profiles and binding characteristics of four HIV-1 envelope glycoprotein (Env) core immunogens using multiple monoclonal antibodies by Bio-Layer Light Interferometry (BLI). This technology enables real-time analysis of interactions on the surface of a fiber optic biosensor by accurately measuring kinetic constants such as Ka, Kd, and KD in a 96-well format.
