This invention discloses “Artificially Cleaved Epitope (ACE)” methods, antibodies, reagents, immunoassays, and kits for designing and detecting mutation-specific epitopes/antigens. The ACE methods can detect epitopes that are either absent or poorly recognizable or accessible naturally to antibodies, and thus must be specifically and artificially created (free terminals) and/or exposed in samples and sample preparations for antibody detection. The ACE methods comprise ACE antigen design and ACE antigen detection. The ACE methods, antibodies, reagents, immunoassays, and kits are useful in research and discovery, diagnostic, and therapeutic applications. In another aspect, the ACE methods can artificially and specifically expose hidden antigens while reducing the antibody non-specific bindings in all antibody-based applications.
本发明公开了用于设计和检测突变特异性表位/抗原的 "人工裂解表位(ACE)"方法、抗体、试剂、免疫测定和试剂盒。ACE 方法可检测抗体不存在或不易识别或不易自然获得的表位,因此必须在样品和样品制备物中特异性地人工创建(游离终端)和/或暴露,以检测抗体。ACE 方法包括 ACE 抗原设计和 ACE 抗原检测。ACE 方法、抗体、试剂、免疫测定和试剂盒可用于研究和发现、诊断和治疗应用。另一方面,ACE 方法可以人工特异性地暴露隐藏的抗原,同时在所有基于抗体的应用中减少抗体的非特异性结合。
