Deciphering a conformation-specific epitope of hCG-beta through Immunokinetics.

Proteins and peptides are comprised of both sequence-specific and conformation-specific epitopes. Sequence-specific epitopes are delineated by a peptide approach and other robust methods like competition assays, gene expression assays, synthetic peptide library based assays, etc. Available methods for deciphering conformation-specific epitopes are cumbersome (X-ray crystallography, etc.

Kinetic analysis of a human chorionic gonadotropin-beta epitope-paratope interaction.

Kinetics of protein-protein or ligand-ligate interaction has predominantly been studied by optical spectroscopy (particularly fluorescence) and surface plasmon resonance biosensors. Almost all such studies are based on association kinetics between ligand-ligate and suffer from certain methodological and interpretational limitations. Therefore, kinetic analyses of dissociation data of such interactions become indispensable.
