Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at -20°C or -80°C. Avoid freeze / thaw cycle.

    pH: 7.50
    Constituents: 0.61% Tris, 0.75% Glycine, 5% Trehalose, Sodium chloride

    Lyophilized from 0.22 µm filtered solution.
    5-10% trehalose is commonly used for freeze drying, and after reconstitution, the trehalose is mostly about 3-5%

    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • Reconstitution
    It is recommended to reconstitute the lyophilized product in sterile deionized water to a final concentration of 1 mg/mL. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

  • Function

    Receptor involved in the costimulatory signal essential for T-lymphocyte proliferation and interleukin-2 production, by binding CD28 or CTLA-4. May play a critical role in the early events of T-cell activation and costimulation of naive T-cells, such as deciding between immunity and anergy that is made by T-cells within 24 hours after activation. Isoform 2 interferes with the formation of CD86 clusters, and thus acts as a negative regulator of T-cell activation.
  • Tissue specificity

    Expressed by activated B-lymphocytes and monocytes.
  • Sequence similarities

    Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Post-translational

    Polyubiquitinated; which is promoted by MARCH8 and results in endocytosis and lysosomal degradation.
  • Cellular localization
