製品の概要

  • 製品名
  • 製品の詳細
    Rabbit polyclonal to TNF alpha
  • 特異性
    No reactivity is detected against human TNF-b (lymphotoxin). This antibody will recognize the cell-bound precursor of TNFa as a 26,000 protein in immunoblots, particularly in denatured samples. This antibody is also useful for neutralization of human and primate TNFa activity in bioassays. It does not neutralize the biological activity of lymphotoxin.

ターゲット情報

  • 機能
    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.
  • 関連疾患
    Genetic variations in TNF are a cause of susceptibility psoriatic arthritis (PSORAS) [MIM:607507]. PSORAS is an inflammatory, seronegative arthritis associated with psoriasis. It is a heterogeneous disorder ranging from a mild, non-destructive disease to a severe, progressive, erosive arthropathy. Five types of psoriatic arthritis have been defined: asymmetrical oligoarthritis characterized by primary involvement of the small joints of the fingers or toes; asymmetrical arthritis which involves the joints of the extremities; symmetrical polyarthritis characterized by a rheumatoidlike pattern that can involve hands, wrists, ankles, and feet; arthritis mutilans, which is a rare but deforming and destructive condition; arthritis of the sacroiliac joints and spine (psoriatic spondylitis).
  • 配列類似性
    Belongs to the tumor necrosis factor family.
  • 翻訳後修飾
    The soluble form derives from the membrane form by proteolytic processing.
    The membrane form, but not the soluble form, is phosphorylated on serine residues. Dephosphorylation of the membrane form occurs by binding to soluble TNFRSF1A/TNFR1.
    O-glycosylated; glycans contain galactose, N-acetylgalactosamine and N-acetylneuraminic acid.

  • ab6671 staining TNF alpha in Cynomolgus Monkey dendritic cells/macrophages from inlamed skin tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 10% serum for 20 minutes at room temperature; antigen retrieval was by heat mediation in citrate buffer, pH6.0. Samples were incubated with primary antibody (1/100) for 30 minutes at room temperature. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/2000) was used as the secondary antibody.
