    Yes
  • Source
    HEK293 cells
  • Purity by SDS PAGE
    ≥95%
  • Assay
    SDS-PAGE
  • Biological activity
    Measured by its ability to inhibit the TNFα mediated cytotoxicity in the L-929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is typically 0.05-0.5 ug/mL in the presence of 0.25 ng/mL rhTNFα.
  • Results
    Measured by its ability to inhibit the TNFα mediated cytotoxicity in the L-929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is typically 0.05-0.5 ug/mL in the presence of 0.25 ng/mL rhTNFα.
  • Molecular Weight
    This protein is fused with a C-terminal 6×his tag, has a calculated MW of 26 kDa. The predicted N-terminus is Leu23. Protein migrates as 23-26 kDa in reduced SDS-PAGE due to glycosylation.
  • Storage Temp
    -20°C
  • Shipping
    Gel Pack
  • Shelf Life
    12 months
  • Appearance
    Lyophilized
  • Physical form description
    Lyophilized from 0.22 um filtered solution in PBS, pH7.4. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization.
  • Reconstitution Instructions
    Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.
  • Background Information
    TNF RI (also known as the p60 or p55 TNFR) and TNF RII (the p75 or p80 TNFR) are two distinct type I transmembrane glycoproteins that bind TNF with high affinity. Both RI and RII are prototypic members of the TNF receptor superfamily and have been designated TNFRSF1A and TNFRSF1B, respectively. Human TNF RII cDNA encodes a 461 amino acid (aa) residue precursor protein with a 22 aa putative signal peptide, a 235 aa extracellular domain, a 20 aa transmembrane domain and a 174 aa cytoplasmic domain. TNFRII is expressed in fetal brain. The protein is produced naturally as a soluble form (sTNFRII). The soluble receptor inhibits TNFα action by competing with cell surface receptors in binding TNFα, thereby blocking its biologic effects. TNFRII is strongly expressed at the cartilage–pannus junction, and plays a major role in a subset of families with multiple cases of rheumatoid arthritis (RA). Further, high plasma levels of sTNFRII were significantly associated with increased incidence of coronary heart disease, independent of established cardiovascular risk factors, and seems to be useful for monitoring the inflammatory activity of sarcoidosis.
  • Handling
    Centrifuge the vial prior to opening.
  • Usage
    For Research Use Only! Not to be used in humans
  • Properties
    Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
