Immunohistochemistry (IHC - Paraffin), Western Blot (WB)

IHC-P (10 ug/ml). WB (0.5 - 2 ug/ml). Usage :Immunohistochemistry: MBS241873 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for MBS241873 was determined to be 10 ug/ml.

Family: TNF

Simultaneously four different laboratories identified a new member of the tumor necrosis factor (TNF) family. This has been named as TALL-1 (6), THANK (TNF homologue that activates apoptosis, nuclear factor-kappaB, and c-Jun NH2- terminal kinase (5), BAFF (for B cell activating factor belonging to the TNF family) (4) and Blys (B lymphocyte stimulator) (3). Membrane-bound BAFF is processed and secreted through the action of a protease whose specificity matches that of the furin family of proprotein convertases. Secreted BLyS/BAFFITHANK acts as a potent B cell growth factor. This protein is expressed abundantly in peripheral blood lymphocytes, specifically in monocytes and macrophages. Its regulation is upregulated by interferon gamma. Overexpression of BLyS/BAFF in transgenic mice lead to increased numbers of mature B and effector T cells. These mice also develop autoimmune like symptoms, such as, high levels of rheumatoid factors, anti-DNA autoantibodies, etc. (2). Recently, two receptors for BLyS/BAFF have been identified and termed as BCMA and T ACI (1). Members in the TNF superfamily regulate immune responses and induce apoptosis. A novel member in the TNF family was recently identified by several groups and designated BAFF (for B cell Activating Factor belonging to the TNF Family), BLyS (for B Lymphocyte Stimulator), TALL-1 (for TNF- and ApoL-related Leukocyte-expressed Ligand), and THANK (for TNF Homologue that Activate Apoptosis, NF-kB and c-jun N-terminal Kinase). BAFF/BLyS was characterized as a B cell activator since it induced B cell proliferation and immunoglobulin secretion. Three receptors for BAFF were recently identified and designated TACI, BCMA and BAFF-R. BAFF and its receptors are essential for B cell development, survival, and humoral immune responses. BAFF is involved in the development of autoimmune diseases including systemic lupus erythaematosus and rheumatoid arthritis.

The protein encoded by this gene is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for receptors TNFRSF13B/TACI, TNFRSF17/BCMA, and TNFRSF13C/BAFFR. This cytokine is expressed in B cell lineage cells, and acts as a potent B cell activator. It has been also shown to play an important role in the proliferation and differentiation of B cells. Alternatively spliced transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Mar 2011]

BAFF: 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. Belongs to the tumor necrosis factor family. 2 isoforms of the human protein are produced by alternative splicing. Protein type: Cell cycle regulation; Apoptosis; Cytokine; Membrane protein, integral. Chromosomal Location of Human Ortholog: 13q32-q34. Cellular Component: extracellular space; perinuclear region of cytoplasm; cytoplasm; plasma membrane; integral to membrane. Molecular Function: protein binding; cytokine activity; tumor necrosis factor receptor binding; receptor binding. Biological Process: cell proliferation; B cell costimulation; B cell homeostasis; immunoglobulin secretion; T cell costimulation; positive regulation of cell proliferation; positive regulation of germinal center formation; positive regulation of B cell proliferation; positive regulation of T cell proliferation; immune response; signal transduction
