The HLA-DRB1 Monoclonal Antibody (CAB19835) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, produced through immunization of rabbits, exhibits high specificity and reactivity towards human samples, making it a reliable choice for various applications, including Western blot analysis.HLA-DRB1 is a major histocompatibility complex (MHC) class II molecule that plays a crucial role in antigen presentation to T cells, thereby initiating adaptive immune responses. Dysregulation of HLA-DRB1 expression or function has been linked to various autoimmune diseases, making it a focal point in research aimed at understanding immune system disorders.
This antibody is validated for use in WB, IHC-P, ELISA applications and has demonstrated reactivity against Human samples.

HLA-DRB1 belongs to the HLA class II beta chain paralogs. The class II molecule is a heterodimer consisting of an alpha (DRA) and a beta chain (DRB), both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells. The beta chain is approximately 26-28 kDa. It is encoded by 6 exons. Exon one encodes the leader peptide; exons 2 and 3 encode the two extracellular domains; exon 4 encodes the transmembrane domain; and exon 5 encodes the cytoplasmic tail. Within the DR molecule the beta chain contains all the polymorphisms specifying the peptide binding specificities. Hundreds of DRB1 alleles have been described and some alleles have increased frequencies associated with certain diseases or conditions. For example, DRB1*1302 has been related to acute and chronic hepatitis B virus persistence. There are multiple pseudogenes of this gene.
