|Specificity:||The antibody 87G recognizes both membrane-bound and soluble forms of HLA-G (HLA-G1 and HLA-G5). HLA-G belongs to the MHC Class I molecules (MHC Class Ib; nonclassical) and it is expressed on the surface of trophoblast cells.
The antibody 87G blocks interaction of HLA-G with inhibitory receptors.
|Immunogen:||HLA-B27 transgenic mice were imunized with H-2 identical murine cells transfected with and expressing genes encoding HLA-G and human beta2-microglobulin.|
|Negative Species:||Mouse, Rat|
|Preparation:||The purified antibody is conjugated with Biotin-LC-NHS under optimum conditions. The reagent is free of unconjugated biotin.|
|Storage Buffer:||Phosphate buffered saline (PBS) with 15 mM sodium azide, approx. pH 7.4|
|Storage / Stability:||Store at 2-8°C. Do not freeze. Do not use after expiration date stamped on vial label.|
|Usage:||The reagent is designed for Flow Cytometry analysis of cells expressing HLA-G molecule on the cell surface, and for ELISA.
Suggested working dilution for Flow Cytometry is 1:500. Indicated dilution is recommended starting point for use of this product. Working concentrations should be determined by the investigator.
|Expiration:||See vial label|
|Lot Number:||See vial label|
