CA 2386066

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 embryo for in vitro fertilization is disclosed. A sandwich ELISA test is provide 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-A2, HLA-B4, HLA-C, or mixed WBC preparations.

L'invention concerne la détection de HLA-G, ainsi que des anticorps dirigés à la fois contre HLA-G soluble et lié à la membrane. A titre d'exemples d'anticorps, on peut citer 2C/C8, 3C/G4, et 4H84. Les anticorps 2C/C8 et 4H84 se lient à la même région de HLA-G, laquelle est différente de la région à laquelle se lie 3C/G4. L'invention concerne encore des procédés de détection et de diagnostic, de même que des nécessaires, notamment un dosage miniaturisé conçu pour un milieu clinique. En outre, l'invention concerne un procédé de sélection d'un embryon destiné à une fertilisation <i>in vitro</i>. L'invention concerne enfin un test ELISA sandwich dans lequel on utilise deux anticorps qui se lient à HLA-G au niveau de régions différentes. Le test de HLA-G de l'invention est plus de mille fois sélectif dans sa liaison à HLA-G que dans sa liaison à HLA-A2, HLA-B4, HLA-C, ou à des préparations WBC mélangées.
