Anti-HLA-DPB1 antibody produced in rabbit

产品说明

一般描述

HLA-DPB1 (major histocompatibility complex, class II, DP β 1) belongs to HLA (human leukocyte antigen) class II family of molecules, which are heterodimers of α and β chains. It is present on human chromosome 6p21.3. It is a highly polymorphic glycoprotein which is present on the surface of antigen presenting cells (APCs). The α and β chains of HLA-DPB1 have two extracellular domains, a hydrophobic transmembrane region and a hydrophilic cytoplasmic tail. It has two α and β chain types- DPα1 and DPα2, and DPβ1 and DPβ2, where DPα2 and DPβ2 are pseudogenes.

免疫原

HLA class II histocompatibility antigen, DP(W4) β-chain precursor recombinant protein epitope signature tag (PrEST)

应用

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

生化/生理作用

HLA-DPB1 (major histocompatibility complex, class II, DP β 1) recognizes and presents antigens to T-helper cells. Polymorphisms in this gene are linked to the differences and level of response to rubella vaccination. Variants of this gene are associated with systemic sclerosis, where DPB1*03:01 and *13:01 alleles are up-regulated. Patients with DPB1*03:01 allele also had higher chances of developing pulmonary fibrosis. HLA-DPB1 05:01 allele is associated with long-term memory against hepatitis B surface antigen (HBsAg), following hepatitis B vaccination. Mismatch in HLA-DPB1 allele during hematopoietic cell transplantation, from an unrelated donor, increases the risk acute graft-versus-host disease (aGVHD).

特点和优势

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
