Preparation and Storage
Stability and Storage
Shipped at 4°C. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
Lyophilised from 0.2 µm filtered solution.
This product is an active protein and may elicit a biological response in vivo, handle with caution.
ReconstitutionWe recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at = -20 °C. Further dilutions should be made in appropriate buffered solutions.
- p75 TNF receptor
FunctionReceptor 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 similaritiesContains 4 TNFR-Cys repeats.
modificationsPhosphorylated; 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 localizationSecreted and Cell membrane.
