The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use 10µl for 106 cells. ab91357-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
FunctionNegatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg), in the suppression of tumor-associated antigen-specific T-cell immunity. Involved in promoting epithelial cell transformation.
Tissue specificityOverexpressed in breast, ovarian, endometrial, renal cell (RCC) and non-small-cell lung cancers (NSCLC). Expressed on activated T- and B-cells, monocytes and dendritic cells, but not expressed in most normal tissues (at protein level). Widely expressed, including in kidney, liver, lung, ovary, placenta, spleen and testis.
Sequence similaritiesBelongs to the immunoglobulin superfamily. BTN/MOG family. Contains 2 Ig-like V-type (immunoglobulin-like) domains.
Cellular localizationCell membrane. Expressed at the cell surface. A soluble form has also been detected.
