NOVEL ASSAY FOR THE DETECTION OF AN ANTIBODY BOUND TO A CELL MEMBRANE RECEPTOR

摘要

This invention relates to the design of a novel immunoassay specific for the measurement of humanized antibody, Campath-1H, bound to the CD52 cell membrane receptor. The method can be used for pharmacokinetic studies and for monitoring purposes. The invention reveals improvements in higher specificities and sensitivities that can be obtained in relation to the conventionally used methods.
