Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at 4°C (stable for up to 12 months). Store at -20°C or -80°C. Avoid freeze / thaw cycle. For long term storage it is recommended to add a carrier protein on reconstitution (0.1% HSA or BSA).

    pH: 7.40
    Constituents: PBS, 5% Trehalose

    Lyophilized from 0.22 µm filtered solution.

  • Reconstitution
    It is recommended to reconstitute the lyophilized product in 1000 µl sterile deionized water to a final concentration of 1 mg/ml. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing.

  • Function

    Negatively 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 specificity

    Overexpressed 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 similarities

    Belongs to the immunoglobulin superfamily. BTN/MOG family.
    Contains 2 Ig-like V-type (immunoglobulin-like) domains.
  • Post-translational
    modifications

    N-glycosylated.
  • Cellular localization

    Cell membrane. Expressed at the cell surface. A soluble form has also been detected.
  • Information by UniProt

Images
