Invitrogen™ RT1.D Monoclonal Antibody (OX-17), FITC

Descripción

anti-rat RT1.D monoclonal antibody recognizes a monomorphic determinant on the α chain of the rat Ia antigen and appears to be the rat homologue of mouse Ia-E. It recognizes the rat Ia product present on B, but not T cells from lymph node or thoracic duct lymph. It does not bind to thymocytes or erythrocytes. The antibody does not cross-react with rat Ia-A or mouse Ia-E antigen, but rabbit antibody raised against the antibody affinity column-purified MRC OX-17 antigen cross-reacted on tissues of mice expressing Ia-E mouse antigen but not on those mouse strains that were Ia-E antigen negative.

RT1.D is a gene located within the major histocompatibility complex (MHC) region of the rat genome, specifically part of the RT1 complex. RT1.D, along with its counterpart RT1.B, comprises class II MHC genes, which are key players in the adaptive immune response. These genes encode for proteins that present extracellularly derived peptides to helper T cells (CD4+ T cells), facilitating the activation and regulation of immune responses. The RT1.D gene product is analogous to human HLA-DR and mouse I-A/I-E molecules, playing an essential role in antigen presentation and immune recognition. RT1.D genes are highly polymorphic, which influences susceptibility to various diseases and are often utilized in studies involving autoimmune diseases, immune response, and transplantation immunology.
