  • Function

    Involved in the presentation of foreign antigens to the immune system. Plays a role in maternal tolerance of the fetus by mediating protection from the deleterious effects of natural killer cells, cytotoxic T lymphocytes, macrophages and mononuclear cells.
  • Tissue specificity

    Expressed in trophoblasts.
  • Sequence similarities

    Belongs to the MHC class I family.
    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.

I don't expect any problems with the ab4570 as this one works fine in IP as well, however, I am not sure about the ab42454.

Nonetheless, I am not too concerned either: ab42454 is not tested in IP, but it works in ELISA, which is a good indicator that it will react with the native protein.

Antibodies MEM-G/9 and MEM-G/11 recognize HLA-G1 (full length) but not truncated isoforms (G2, G3, G4) on the cell surface. Both react with HLA-G5 (G6 was not rigorously tested), i.e. the soluble isoform. MEM-G/11 reacts with a different epitope than MEM-G/9, this could be useful in double staining (MEM-G/11 is available as FITC and MEM-G/9 as PE conjugate) of cell surface HLA-G1. In a soluble form (actively secreted G5 or shedded G1), it was not demonstrated that both mAbs can be used as pair in sandwich ELISA.
