  • Product overview

    Abcam’s Human BAFF (TNFSF13B) in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Human BAFF (TNFSF13B) in cell culture supernatants, serum and plasma (heparin, EDTA).


    A BAFF (TNFSF13B) specific mouse monoclonal antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells and incubated. A biotinylated detection polyclonal antibody from goat, specific for BAFF (TNFSF13B) is then added followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. TMB is then used to visualize the HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The density of yellow coloration is directly proportional to the Human BAFF (TNFSF13B) amount of sample captured in plate.


    For higher sensitivity in only 90 minutes, we recommend Human BAFF ELISA Kit (TNFSF13B) (ab188391) from our SimpleStep ELISA® range.

Properties

  • FunctionCytokine 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.
    Isoform 2 seems to inhibit isoform 1 secretion and bioactivity.
  • Tissue specificityAbundantly 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. Isoform 2 is expressed in many myeloid cell lines.
  • Sequence similaritiesBelongs to the tumor necrosis factor family.
  • Post-translational
    modifications
    The soluble form derives from the membrane form by proteolytic processing.
    Isoform 2 is not efficiently shed from the membrane unlike isoform 1.
    N-glycosylated.

1.) Yes, a washing step is needed. This washing step is carried out when following the preparation of the plate under point 7 A.

This plate preparation should be done immediately before starting the assay procedure.

2.) No...
