METHOD FOR CLEAVING AND DEGLYCOSYLATING ANTIBODIES TO PROMOTE LIGAND BINDING

摘要

The present invention details methods to detect glycoproteins in samples to identify a disease state. In particular, an improved sandwich assay is described, using both an antibody and an array of lectins. Methods for increasing the efficiency of interaction of an antibody with a ligand by cleaving the antibody to remove the carbohydrate moiety, and orienting the cleaved fragment on a matrix to enhance recognition of a ligand are also described. Methods of differentiating pregnancy-derived and disease derived samples are also described.
