BD, 557577, Purified Mouse Anti-human HLA-G Denatured 4H84

HLA-G is a HLA class I molecule, but it is distinct from other class I molecules because of its quasi-monomorphism and restricted tissue distribution. It can be expressed as seven distinct protein forms. HLA-G1, -G2, G3, and -G4 are membrane bound while HLA-G5, -G6, and G7 are soluble. HLA-G is expressed in healthy individuals on amniocytes and cytotrophoblasts in the amnion-chorion. HLA-G interacts with inhibitory receptors such as ILT-2, ILT-4, p49 and KIR2DL4 expressed on NK cells, shifts the cytokine balance towards Th2 dominance, suppresses the proliferation of allogeneic CD4 lymphocytes and, in its soluble form, induces apoptosis of activated CD8 cells and inhibits cytolysis by NK cells.
Recommended Assay Procedure: This product is routinely tested on fixed and permeabilized (BD Cytofix/Cytoperm™, Cat. No. 554714) JEG-3 cell line by flow cytometry. It's also suitable for Western blotting and for staining acetone-fixed frozen tissue sections at 1-10 µg/ml and formalin fixed paraffin tissue sections at 1-10 µg/ml with citrate buffer pretreatment.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
