Product Summary for HLA G Antibody (01G) [PE/Atto594]
Immunogen
HLA-B27 transgenic mice were imunized with H-2 identical murine cells transfected with and expressing genes encoding HLA G Antibody (01G) and human beta2-microglobulin.
Specificity
The antibody 01G recognizes membrane-bound form of HLA-G (full-length HLA-G1), but not soluble forms. HLA-G belongs to the MHC Class I molecules (MHC Class Ib; nonclassical) and it is expressed on the surface of trophoblast cells.
Clonality
Monoclonal
Host
Mouse
Isotype
IgG1
Applications for HLA G Antibody (01G) [PE/Atto594]
Application
Recommended Usage
Flow Cytometry
Optimal dilutions of this antibody should be experimentally determined.
Application Notes
Optimal dilution of this antibody should be experimentally determined. For optimal results using our Tandem dyes, please avoid prolonged exposure to light or extreme temperature fluctuations. These can lead to irreversible degradation or decoupling. When staining intracellular targets, specific attention to the fixation and permeabilization steps in your flow protocol may be required. Please contact our technical support team at technical@novusbio.com if you have any questions.

Background: HLA-G
Discovered in cytotrophoblasts, HLA-G is involved in fetal maternal immune tolerance and some studies have linked its downregulation with severe preeclampsia (3). HLA-G mediated immune suppression works by impeding cell proliferation, differentiation, cytotoxicity, cytokine secretion and chemotaxis; and activation of regulatory cells and MDSCs or M2 type macrophage. HLA-G is constitutively expressed in immune-privileged sites such as pancreatic islets, mesenchymal stem cells (MSCs) and the cornea. Upregulation of HLA-G occurs in pathological states including cancer, allo-transplantations, viral infections, autoimmune and inflammatory diseases (4). In cancer, HLA-G expression is induced by hypoxia and has been correlated with advanced tumor stage, tumor metastasis, and poor therapeutic response and survival. HLA-G is an attractive tumor associated-antigen (TAA) for immunotherapy and is considered a major immune checkpoint (ICP).
