Our Abpromise guarantee covers the use of ab37170 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 10 µg/ml.
WB Use a concentration of 0.5 - 1 µg/ml. Detects a band of approximately 37 kDa (predicted molecular weight: 27 kDa). TWEAK may migrate at aberrant poitions in SDS-PAGE.
ICC/IF Use a concentration of 10 µg/ml.


  • FunctionBinds to FN14 and possibly also to TNRFSF12/APO3. Weak inducer of apoptosis in some cell types. Mediates NF-kappa-B activation. Promotes angiogenesis and the proliferation of endothelial cells. Also involved in induction of inflammatory cytokines.
  • Tissue specificityHighly expressed in adult heart, pancreas, skeletal muscle, brain, colon, small intestine, lung, ovary, prostate, spleen, lymph node, appendix and peripheral blood lymphocytes. Low expression in kidney, testis, liver, placenta, thymus and bone marrow. Also detected in fetal kidney, liver, lung and brain.
  • Sequence similaritiesBelongs to the tumor necrosis factor family.
  • Post-translational
    The soluble form derives from the membrane form by proteolytic processing.
  • Cellular localizationSecreted and Cell membrane.

  • ICC/IF image of ab37170 stained SKNSH cells. The cells were 4% formaldehyde (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab37170, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
