CENPBD1抗体—艾普蒂

The CENP-B (Centromere Protein B) antibody is a significant tool in studying centromere biology and autoimmune disorders. CENP-B is a highly conserved protein involved in centromere assembly and chromosome segregation during cell division. It binds to centromeric α-satellite DNA through a 17-bp motif (CENP-B box), facilitating kinetochore formation and ensuring proper chromosome alignment. Antibodies targeting CENP-B are frequently detected in autoimmune conditions, particularly in a subset of patients with systemic sclerosis (scleroderma) and related disorders, where they serve as diagnostic biomarkers. These autoantibodies are associated with limited cutaneous involvement and a lower risk of severe organ complications. In research, CENP-B antibodies are used to investigate centromere structure, epigenetic regulation, and mitotic mechanisms. Commercial CENP-B antibodies are generated using immunogens from conserved regions of the protein (e.g., N-terminal DNA-binding domain) and validated in applications like immunofluorescence, Western blotting, and chromatin immunoprecipitation. Their specificity helps distinguish CENP-B from other centromere proteins (e.g., CENP-A, CENP-C) in functional studies. Understanding CENP-B antibody interactions also contributes to exploring autoimmune pathogenesis and developing targeted therapies.
