Abstract

The present invention relates to the detection of HLA-G. Antibodies to both soluble and membrane bound HLA-G are disclosed. Exemplary antibodies include 2C/C8, 3C/G4, and 4H84. 2C/C8 and 4H84 antibodies bind to the same region of HLA-G, which is a different region than that bound by 3C/G4. Methods of detection and diagnosis are disclosed as well as kits, including a miniaturized assay suitable for a clinical setting. Further, a method of selecting an embryos for in vitro fertilization is disclosed. A sandwich ELISA test is provided using two antibodies that bind to HLA-G at different regions. The HLA-G test according to the invention is over 1000 times more selective in binding to HLA-G than to antigens HLA-A , HLA-B , HLA-C, or mixed WBC preparations.
