There are two classes of HLA antigens: class I and class II. This class I molecules are membrane glycoproteins composed of a heavy (alpha) chain which is encoded by a HLA class I gene, and β2-microglobulin light (beta) chain. The most extensively characterized members of the HLA class I gene family are the genes encoding the major transplantation antigenes, HLA-A, B and C. HLA-E is a non-classical MHC class I molecule. HLA-E is frequently overexpressed in tumor diseases, transplants and virus-infected cells and represents an immunomodulatory molecule by binding to the receptors CD94/NKG2A, -B and -C on NK and T cells. Due to its immune suppressive features HLA-E expression might represent an important mechanism of tumors to escape immune surveillance.(PMID: 667938; 3375250; 2249951; 27589686) Specification Tested Reactivity: human, mouse Host / Isotype: Rabbit / IgG Class: Polyclonal Type: Antibody Immunogen: CatNo: Ag26581 Product name: Recombinant human HLA-E protein Source: e coli. -derived, PGEX-4T Tag: GST Domain: 72-200 aa of BC002578 Sequence: WMEQEGSEYWDRETRSARDTAQIFRVNLRTLRGYYNQSEAGSHTLQWMHGCELGPDRRFLRGYEQFAYDGKDYLTLNEDLRSWTAVDTAAQISEQKSNDASEAEHQRAYLEDTCVEWLHKYLEKGKETL Predict reactive species Full Name: major histocompatibility complex, class I, E Calculated Molecular Weight: 40 kDa Observed Molecular Weight: 40-42 kDa GenBank Accession Number: BC002578 Gene Symbol: HLA-E Gene ID (NCBI): 3133 RRID: AB_2880865 Conjugate: Unconjugated Form: Liquid Purification Method: Antigen affinity purification UNIPROT ID: P13747 Storage Buffer: PBS with 0.02% sodium azide and 50% glycerol, pH 7.3.
