  • Specification
  • Product Description:
  • Mouse monoclonal antibody raised against HLA-DR.
  • Immunogen:
  • Native from thymocyte membrane.
  • Host:
  • Mouse
  • Reactivity:
  • Human
  • Specificity:
  • This antibody recognizes common epitope on human HLA-DR which is dependent on the association of alpha and beta chains. DR is the isotype of human MHC Class II molecules expressed on antigen-presenting cells (APC; dendritic cells, B lymphocytes, monocytes, macrophages).
  • Form:
  • Liquid
  • Conjugation:
  • PE
  • Isotype:
  • IgG1
  • Recommend Usage:
  • Flow Cytometry (20 ul in human blood cells 100 ul in whole blood or 106 cells in a suspension)
    The optimal working dilution should be determined by the end user.
  • Storage Buffer:
  • In PBS (0.2% BSA, 15 mM sodium azide)
  • Storage Instruction:
  • Store in the dark at 4°C. Do not freeze.
    Avoid prolonged exposure to light.
    Aliquot to avoid repeated freezing and thawing.
  • Note:
  • This product contains sodium azide: a POISONOUS AND HAZARDOUS SUBSTANCE which should be handled by trained staff only.

  • Gene Information
  • Entrez GeneID:
  • 3122
  • Gene Name:
  • HLA-DRA
  • Gene Alias:
  • HLA-DRA1
  • Gene Description:
  • major histocompatibility complex, class II, DR alpha
  • Gene Summary:
  • HLA-DRA is one of the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha and a beta chain, 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 (APC: B lymphocytes, dendritic cells, macrophages). The alpha chain is approximately 33-35 kDa and its gene contains 5 exons. Exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, and exon 4 encodes the transmembrane domain and the cytoplasmic tail. DRA does not have polymorphisms in the peptide binding part and acts as the sole alpha chain for DRB1, DRB3, DRB4 and DRB5. [provided by RefSeq

  • Gene Description:
  • major histocompatibility complex, class II, DR beta 1
  • Gene Summary:
  • 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 (APC: B lymphocytes, dendritic cells, macrophages). 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 typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. DRB1 is expressed at a level five times higher than its paralogs DRB3, DRB4 and DRB5. DRB1 is present in all individuals. Allelic variants of DRB1 are linked with either none or one of the genes DRB3, DRB4 and DRB5. There are 4 related pseudogenes: DRB2, DRB6, DRB7, DRB8 and DRB9. [provided by RefSeq
