Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.

    pH: 7.00
    Constituents: 0.75% Glycine, 0.48% Tris, L-Arginine, 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 protein in 200µl sterile deionized water to a final concentration of 1mg/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
    modifications

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

    Membrane.
  • Information by UniProt

Images

  • Human B7-2, Fc Tag on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
  • FACS assay shows that Human B7-2, Fc Tag can bind to 293T cells overexpressing human CTLA4 protein. The concentration of Human B7-2 is 3 µg/ml.
  • FACS analysis shows that the binding of Human B7-2, Fc Tag to CD28 expressed on Jurkat E6.1 was inhibited by increasing concentration of neutralizing� anti-CD28 antibody. The concentration of B7-2 used is 2 µg/ml. The IC50 is 0.022 µg/ml.
  • Flow Cytometry assay shows that recombinant Human B7-2, Fc Tag can bind to CD28 expressed on Jurkat E6.1. The concentration of B7-2 used is 2 µg/ml(Routinely tested).
  • Immobilized Human B7-2, Fc Tag at 5 µg/mL (100 µL/well) can bind Biotinylated Human CTLA-4, Fc Tag, Avi Tag with a linear range of 0.6-10 ng/mL.
  • SDS-PAGE of reduced ab167720 stained overnight with Coomassie Blue.
