Description
HLA-E (human leukocyte antigen E) is a non-classical MHC I antigen, which is important for dialogue with NK cells and their regulation through interaction with CD94/NKG2 receptor. Like other MHC I molecules, transmembrane HLA-E molecule (45 kDa) associates with beta2 microglobulin. Unlike HLA-G, expression of HLA-E molecules is not so restricted, but it has been detected at least at mRNA level in virtually all cells and tissues examined. In peripheral blood, HLA-E protein is expressed at least in all mononuclear cells, but in different quantity (B cells and monocytes more than T cells and NK cells) .

Storage Conditions
Store at 2-8°C. Do not freeze.
Specificity
The antibody MEM-E/07 recognizes an extracellular epitope on native surface-expressed HLA-E, but not denaturated heavy chain of HLA-E. HLA-E belongs to the MHC Class I molecules (MHC Class Ib; nonclassical) and it is expressed on many types of the human cells. The published results revealed that the antibody cross-reacts with some classical MHC Class I molecules (MHC Class Ia) : HLA-B7 (strongly), HLA-B8 (moderately), HLA-B27, -B44 (weakly) .
Applications Notes
Immunohistochemistry (paraffin sections) : Recommended dilution: 10 μg/ml; positive tissue: spleen. Flow cytometry: Recommended dilution: 1-4 µg/ml
Isotype
Mouse IgG1
