Further dilutions can be made in assay buffer.

Small volumes of anti-HLA-G antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Beta-2-microglobulin (B2M) is found in the serum of normal individuals and in the urine in elevated amounts in patients with Wilson disease, cadmium poisoning, and other conditions leading to renal tubular dysfunction. Like immunoglobulins, prealbumin, and the beta protein found in the amyloid of Alzheimer disease, B2M has a predominantly beta-pleated sheet structure that may adopt the fibrillar configuration of amyloid in certain pathologic states. The protein is a single polypeptide chain of molecular weight 11,600 (human 119aa, chromosome 15). B2M associates with heavy chain of class I MHC antigens on the cell surface. A transient complex of MHC-heavy chain and B2M is known to be assembled into the TAP molecule involving interation with a number of chaperones. Binding of the processed peptide releases the class I-B2M complex to the cell surface. Absence of binding leads to degradation in the proteasome. Progressive hepatic iron overload, indistinguishable from that observed in HFE, was found only in mice homozygous for the mutated B2M gene.

HLA-G protein

O02923_HUMAN

HLA-G belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane. HLA-G is expressed on fetal derived placental cells. The heavy chain is approximately 45 kDa and its gene contains 8 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the alpha1 and alpha2 domain, which both bind the peptide, exon 4 encodes the alpha3 domain, exon 5 encodes the transmembrane region, and exon 6 encodes the cytoplasmic tail.
