Less than 1EU per μg by the LAL method.

Purity

> 95% as determined by Tris-Bis PAGE

Formulation

Supplied as 0.22μm filtered solution in PBS (pH 7.4).

Storage

The product should be stored at -70℃. Please do not repeated freeze-thaw cycles.

Assay Data
Tris-Bis PAGE

Human HLA-G Free heavy chain on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

Background

HLA-G is a molecule that was first known to confer protection to the fetus from destruction by the immune system of its mother, thus critically contributing to fetal-maternal tolerance. The first functional finding constituted the basis for HLA-G research and can be summarized as such: HLA-G, membrane-bound or soluble, strongly binds its inhibitory receptors on immune cells (NK, T, B, monocytes/dendritic cells), inhibits the functions of these effectors, and so induces immune inhibition.

Synonyms

HLA class I histocompatibility antigen, alpha chain G;sHLA-G;HLA-G
