Product Data
Clone Name utr1
Applications FC, FN, IHC, IP, WB
Recommended Dilution Immunohistology: 2-5 µg/ml on Cryostat Sections (2% Periodate-lysine-paraformaldehyde or acetone for fixation).
Flow Cytometry: 10 µg/ml.
Immunoprecipitation.
Western blots: 30 µg/ml on non-reduced SDS PAGE. The epitope is sensitive to reduction, may need enrichment by Immunoprecipitation.
Functional Assay: This antibody utr1 is useful for studying biological effects of TNF-Receptor p75 in vitro where it inhibits the binding of radiolabelled TNF to Human cells expressing the p75 TNF receptor. In order to completely block TNF binding to the cell surface, 10 µg/ml of utr1 are required. utr1 itself may have an agonistic effect in assays measuring cytotoxicity, fibroblast growth or IL-6 secretion. 
Recommended Positive Control: Human Tonsil.
Reactivities Human
Host Mouse
Isotype IgG1
Clonality Monoclonal
Immunogen Partially purified preparations of TNF binding proteins from U937 cells.
Specificity The antibody reacts with CD120b.
Antigen Distribution
Isolated Cells and Cell lines: U937, HL-60.
Lymphocytes from peripheral blood show a faint staining.
Mitogen stimulation of lymphocytes increases the intensity.
Bone marrow cells are not stained with utr1.
Tissue Sections: Immunohistochemical staining in normal not diseased tissue is confined to the lymphohistiocytic tissue, which includes the thymus and lymphoid organs such as spleen, tonsils, lymph nodes, mucosa, and associated lymphoid tissue (see Ref 7). Expression of p55 and p75 receptors can be detected in different areas where an overlapping is found betweenTNFR p75 and IL-2 receptor expression. The p75 expression can be detected mainly in the T-cell area whereas the p55 expression is restricted to dendritic reticulum cells in the germinal centers.
In non lymphoid organs (kidney, liver, heart, brain, adrenals, uterus, ovary, testes, prostate, stomach, intestines) utr1 recognizes only in kidney some interstitial reticulum cells. Cells which are known to respond to TNF namely endothelial cells, smooth muscle cells and fibroblasts did not show expression of p55 and or p75 TNF receptor (see Ref 7). Investigations on pathological tissues show a TNFR p75 expression on epitheloid cell granulomas and giant cells in sarcoidosis.

Gene Name tumor necrosis factor receptor superfamily member 1B
Background Tumor Necrosis Factor (TNF) is a cytokine whose function is mediated through two distinct cell surface receptors (TNF Receptor I and TNF Receptor II) that are included in the TNF receptor superfamily along with FAS antigen and CD40. TNF receptors I and II are 55 and 75 kDa members, respectively, of a family of cell surface molecules including nerve growth factor receptor, Fas/Apo1, CD30, OX40, and 4-1BB, which are characterized by cysteine rich motifs in the extracellular domain.
TNF Receptor II (p75, CD120b) is present on most cell types (including monocytes, endothelial cells, Langerhans cells, and macrophages) and is considered to play a role in cell stimulation by TNF alpha. TNF Receptor II molecule is shown to be responsible for stimulation of activated T lymphocytes by TNF alpha.
Synonyms Tumor necrosis factor receptor 2, p80 TNF-alpha receptor, TNFRSF1B, TNFBR, TNF-R2
