Antibodies and methods for detecting and isolating the common conjugation site-specific epitopes/antigens

摘要

This invention discloses the “Artificially Cleaved Epitope (ACE)” methods, antibodies, reagents, immunoassays, immunoaffinity isolation, and kits for all antibody-based applications of designing, detecting, or isolating the common ACE epitopes/antigens in a sample. The ACE methods can detect or isolate epitopes that are either absent or poorly accessible naturally to antibodies, and thus must be specifically and artificially created (free terminals) and/or exposed in a sample for antibody-based applications. The common ACE structures are those that are the common parts of different macromolecule-to-macromolecule conjugation segments. The ACE methods, antibodies, reagents, immunoassays, and kits are useful in research and discovery, diagnostic, and therapeutic applications.
