Description

  • Product name

    Recombinant human BAFF protein (Active) (FITC)
    See all BAFF proteins and peptides
  • Biological activity

    Measured by its binding ability in a functional ELISA. Immobilized Human BCMA, Fc Tag at 10 μg/mL (100 μL/well) can bind ab219665 with a linear range of 0.31-1.25 μg/mL.

  • Purity

    > 95 % SDS-PAGE.
    The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with FITC using standard chemical labeling method. The residual FITC is removed by molecular seive treatment during purification process.

Preparation and Storage

  • Stability and Storage

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

    pH: 7.40
    Constituents: 5% Trehalose, PBS

    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 25 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. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

  • Function

    Cytokine that binds to TNFRSF13B/TACI and TNFRSF17/BCMA. TNFSF13/APRIL binds to the same 2 receptors. Together, they form a 2 ligands -2 receptors pathway involved in the stimulation of B-and T-cell function and the regulation of humoral immunity. A third B-cell specific BAFF-receptor (BAFFR/BR3) promotes the survival of mature B-cells and the B-cell response.
  • Tissue specificity

    Abundantly expressed in peripheral blood Leukocytes and is specifically expressed in monocytes and macrophages. Also found in the spleen, lymph node, bone marrow, T-cells and dendritic cells. A lower expression seen in placenta, heart, lung, fetal liver, thymus, and pancreas.
  • Sequence similarities

    Belongs to the tumor necrosis factor family.
  • Post-translational
    modifications

    The soluble form derives from the membrane form by proteolytic processing.
    N-glycosylated.
  • Cellular localization

    Secreted and Cell membrane.
  • Information by UniProt

Images

  • Immobilized Human BCMA (Fc Tag) at 10 µg/mL (100 µL/well) can bind FITC-Labeled Human BAFF (Fc Tag) with a linear range of 0.156-2.5 µg/mL (Ex.488 nm/Em.535 nm) (QC tested).
  • ab219665 on SDS-PAGE  under reducing (R) conditions.

    The gel was stained overnight with Coomassie Blue.

    The purity of the protein is greater than 95%.

    The protein migrates as 55 kDa under reducing (R) conditions due to glycosylation.

  • Immobilized Human BCMA, Fc Tag at 10 μg/L  (100 μL/well) can bind ab219665 with a linear range of 0.31-1.25 μg/mL.
