|WB||1/1000. Detects a band of approximately 30, 32 kDa (predicted molecular weight: 31 kDa).|
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.
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.
Sequence similaritiesBelongs to the tumor necrosis factor family.
modificationsThe soluble form derives from the membrane form by proteolytic processing.
Cellular localizationSecreted and Cell membrane.

BAFF was immunoprecipitated from 0.35 mg of U937 (human histiocytic lymphoma cell line) whole cell lysate with ab224710 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab224710 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.

Flow cytometric analysis of Daudi (human Burkitt's lymphoma cell line; left panel) and HL-60 (human promyelocytic leukemia cell line ;right panel) cell lines labeling BAFF with ab224710 at 1/500 dilution (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) at 1/2000 dilution was used as the secondary antibody.
Negative control: Daudi. (PMID: 20951740)
Gated on viable cells.
Immunofluorescent analysis of 100% methanol-fixed U937 (human histiocytic lymphoma cell line) cells labeling BAFF with ab224710 at 1/100 dilution followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining on U937 cells.
The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) (red) at 1/200 dilution.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution.
Confocal image showing membranous staining in U-937 cells.
We don’t recommend PFA fixation, since the result shows some background staining in the nuclear.
Negative control: HEK-293（PMID: 17393395.
