title: Cell surface detection of HLA-E gene products with a specific monoclonal antibody.
abstract: An HLA-E-specific monoclonal antibody (mAb) was obtained by immunization of human beta2-microglobulin transgenic mice (M-TGM) with spleen cells from double transgenic mice expressing HLA-E molecules (EM-TGM). This mAb, designated V16, specifically recognizes in flow cytometry analysis the HLA-E expressing mouse cells, whereas it does not bind to mouse cells expressing various HLA class I molecules (HLA-A2, -A3, -A11, -A26, A29, -B7, -B27, -Cw3, -Cw7, and HLA-G). V16 mAb binds efficiently to human EBV-infected B lymphocytes, PHA blasts and PBL, thus establishing the surface expression of HLA-E in vivo on these cells.
