TNF alpha Antibody

• Catalog Number: orb2641895
• Category: Antibodies
• Description: Tumor Necrosis Factor Alpha (TNF alpha) is a cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation. Impairs regulatory T-cells (Treg) function in individuals with rheumatoid arthritis via FOXP3 dephosphorylation. Upregulates the expression of protein phosphatase 1 (PP1), which dephosphorylates the key 'Ser-418' residue of FOXP3, thereby inactivating FOXP3 and rendering Treg cells functionally defective. Key mediator of cell death in the anticancer action of BCG-stimulated neutrophils in combination with DIABLO/SMAC mimetic in the RT4v6 bladder cancer cell line. [UniProt]

Immunofluorescent staining of PFA-fixed human HepG2 cells with TNF-alpha antibody (green, clone TMDa1-1) and Reddot nuclear stain (red).

IHC testing of FFPE human histiocytoma and TNF alpha antibody (clone TMDa1-1). Staining of formalin-fixed tissues requires boiling tissue sections in 10 mM Tris buffer with 1 mM EDTA, pH9, for 10-20 min followed by cooling at RT for 20 min.

IHC testing of FFPE rat stomach and TNF alpha antibody (clone TMDa1-1). Staining of formalin-fixed tissues requires boiling tissue sections in 10 mM Tris buffer with 1 mM EDTA, pH9, for 10-20 min followed by cooling at RT for 20 min.

Flow cytometry testing of PFA-fixed human HepG2 cells with TNF-alpha antibody (clone TMDa1-1); Red = isotype control, Blue = TNF-alpha antibody.
