  • 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.

  • ab109322 staining TNF Receptor II in SW480 cells. The cells were fixed with 100% methanol. In our hands PFA fixed cells did not produce good results with this antibody. Nuclear DNA was labelled in blue with DAPI.

  • ab109322, at a 1/100 dilution, staining TNF Receptor II in paraffin embedded Human uterus tissue by Immunohistochemistry.

  • Overlay histogram showing HL60 cells stained with ab109322 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab109322, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

Thank you again for your email, and for your patience.

I've heard back from the lab, and they load 10 ug of protein per lane. None of the cell lines are transfected, and they use the general Epitomics Western blot protocol-

Thank you very much for your reply.

I've asked the lab whether the cells are transfected, and how many micrograms of lysate were loaded.

I'd be happy to send a positive control lysate, however I can't send all of the lysates shown i...

Thank you very much for your call yesterday.

I've received the attached image from the lab, which shows Western blot results using C6, Raw264.7, PC12, and NIH/3T3 cell lysates.

The band probably aligns most closely with the ˜ 60 kDa...
