  • Product overview

    Abcam’s Human STNF-R1 (soluble tumor necrosis factor receptor I) ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human STNF-R1 in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for Human STNF-R1 coated on a 96-well plate. Standards and samples are pipetted into the wells and STNF-R1 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human STNF-R1 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of STNF-R1 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • FunctionReceptor for TNFSF2/TNF-alpha and homotrimeric TNFSF1/lymphotoxin-alpha. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death-inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. Contributes to the induction of non-cytocidal TNF effects including anti-viral state and activation of the acid sphingomyelinase.
  • Involvement in diseaseFamilial hibernian fever
    Multiple sclerosis 5
  • Sequence similaritiesContains 1 death domain.
    Contains 4 TNFR-Cys repeats.
  • DomainThe domain that induces A-SMASE is probably identical to the death domain. The N-SMASE activation domain (NSD) is both necessary and sufficient for activation of N-SMASE.
    Both the cytoplasmic membrane-proximal region and the C-terminal region containing the death domain are involved in the interaction with TRPC4AP.
  • Post-translational
    The soluble form is produced from the membrane form by proteolytic processing.
  • Cellular localizationCell membrane. Golgi apparatus membrane. Secreted. A secreted form is produced through proteolytic processing and Secreted. Lacks a Golgi-retention motif, is not membrane bound and therefore is secreted.
