  • Function

    Receptor with high affinity for TNFSF2/TNF-alpha and approximately 5-fold lower affinity for homotrimeric TNFSF1/lymphotoxin-alpha. The TRAF1/TRAF2 complex recruits the apoptotic suppressors BIRC2 and BIRC3 to TNFRSF1B/TNFR2. This receptor mediates most of the metabolic effects of TNF-alpha. Isoform 2 blocks TNF-alpha-induced apoptosis, which suggests that it regulates TNF-alpha function by antagonizing its biological activity.
  • Sequence similarities

    Contains 4 TNFR-Cys repeats.
  • Post-translational

    Phosphorylated; mainly on serine residues and with a very low level on threonine residues.
    A soluble form (tumor necrosis factor binding protein 2) is produced from the membrane form by proteolytic processing.
  • Cellular localization

    Secreted and Cell membrane.

  • HDMECs were harvested with trypsin and washed three times with ice-cold PBS. Lysis buffer (50 mm Tris-HCl, pH 7.5, 10% of glycerol, 1% of Triton X-100, 300 mm NaCl, 150 mm KCl, 5 mm EDTA, 1 mm dithiothreitol, 0.5 mm Na3VO4, 10 mm NaF, 10 mm iodoacetamide, and protease inhibitors) or SDS gel buffer with ß-mercaptoethanol was then added, and the lysates were cleared of debris by centrifugation. 80 µg of total protein/sample was subjected to 4–15% gradient SDS-PAGE and electrophoretically transferred to polyvinylidene difluoride membranes. Protein blots on the membrane were identified by using ab8161 followed by horseradish peroxidase-conjugated anti-IgG secondary antibodies in blocking buffer. Images were obtained by chemiluminescence on x-ray film using ECL reagents.
  • ICC/IF image of ab8161 stained Hek293 cells. The cells were 4% formaldehyde fixed (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 (ab8161, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 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.

  • Overlay histogram showing HL60 cells stained with ab8161 (red line). The cells were fixed with 80% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab8161, 2µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

    Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.

Thank you for contacting us. We may be able to custom make this antibody in an azide-free form for bulk orders of 10 or more vials. If you are interested in a custom bulk purchase, please contact my colleagues at mailto:sales@abcam.com and they can help put together a quote and estimated availability time for you.

Alternatively, for smaller purchases you could use one of our concentration and clean up kits (ab102778) to perform a buffer exchange and greatly reduce the concentration of azide in the antibody. I hope this helps, please let me know if you need any additional information or assistance.

Thank you for your enquiry. We have just received the following information from the source of ab8161: The antibody to human CD120b, TNF-RII (p75/p80), clone MR2-1 were generated as described in the following article: Leeuwenberg, JFM et al; Slow release of soluble TNF-Receptors by monocytes in vitro. J Immunol 1994, 152: 4036. This article shows that sTNF-R75 was purified from culture supernatant of cells, transfected with the extracellular part of TNF-R75 by affinity chromatography on a TNF-coupled agarose column. We hope this information will be helpful to you. If you have further questions please do not hesitate to contact us.
