Antibody N-Terminal Cyclization Analysis Service

Antibody N-terminal cyclization is a process in which the N-terminal amino acid sequence of an antibody forms a stable cyclic structure through a cyclization reaction. This reaction is typically catalyzed by enzymes such as cyclase, which recognize specific N-terminal sequences. The cyclization alters the antibody's spatial structure, enhancing stability and function, reducing degradation and inactivation, and improving binding affinity to antigens. Additionally, the unique structure of cyclized antibodies may lower immunogenicity, decreasing the likelihood of being recognized as foreign by the immune system. Antibody N-terminal cyclization analysis is a sophisticated technique used to detect and study this modification, aiding in the development and optimization of antibody drugs by providing detailed structural and functional insights.
