Mouse Anti-Human HLA-B7 Antibody (BB7.1)

HLA-B7, also known as HLA-B*07:02, is a specific allele of the human leukocyte antigen B (HLA-B) gene located on the short arm of chromosome 6, encoding a major histocompatibility complex (MHC) class I cell surface receptor that plays a pivotal role in the adaptive immune system by presenting endogenous peptide fragments to CD8+ cytotoxic T cells for immune surveillance. This highly polymorphic protein consists of a heavy chain non-covalently associated with beta-2 microglobulin, forming a groove that binds and displays intracellular peptides derived from normal cellular metabolism or pathogenic infections, thereby enabling the immune system to distinguish self from non-self. Clinically, HLA-B7 is significant not only for its involvement in transplant rejection scenarios due to alloimmune responses but also for its well-documented associations with various autoimmune disorders, such as multiple sclerosis and psoriasis, as well as its potential influence on susceptibility to certain viral infections and cancer progression, making it a critical marker in immunogenetics, personalized medicine, and vaccine development research.
