Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at -80°C.

    pH: 7.40
    Constituents: 0.61% Tris, 0.75% Glycine, 5% Trehalose, 0.44% L-Arginine, 0.87% Sodium chloride

    Note: 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 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 for TNFSF5/CD40LG.
  • Tissue specificity

    B-cells and in primary carcinomas.
  • Involvement in disease

    Defects in CD40 are the cause of hyper-IgM immunodeficiency syndrome type 3 (HIGM3) [MIM:606843]; also known as hyper-IgM syndrome 3. HIGM3 is an autosomal recessive disorder which includes an inability of B cells to undergo isotype switching, one of the final differentiation steps in the humoral immune system, an inability to mount an antibody-specific immune response, and a lack of germinal center formation.
  • Sequence similarities

    Contains 4 TNFR-Cys repeats.
  • Cellular localization

    Secreted and Cell membrane.
  • Information by UniProt


  • Immobilized Rhesus macaque CD40, Fc Tag at 2 µg/mL (100 µL/well) can bind Human CD40 Ligand, His Tag with a linear range of 5-50 ng/mL.
  • SDS-PAGE analysis of reduced ab208480 stained overnight with Coomassie Blue.

    Note: DTT-reduced Protein migrates as 56 kDa in SDS-PAGE.
