Active Recombinant Mouse Tnf Protein (Leu80-Leu235), C-His tagged, Animal-free, Carrier-free

• Cat.No.: Tnf-84M
• Product Overview: Recombinant Mouse Tnf Protein (Leu80-Leu235) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Species: Mouse
• Source: E.coli
• Tag: His
• ProteinLength: Leu80-Leu235
• Description: Tumor necrosis factor alpha (TNF alpha) stimulates the acute phase of the immune response. In response to a pathogen, TNF alpha is one of the first to be released and can apply its effects in many organs. TNF alpha stimulates the release of corticotropic releasing hormone, suppresses appetite, and induces fever, in the hypothalamus. TNF increase vasodilation and loss of vascular permeability, it helps recruit lymphocyte, neutrophil, and monocyte to the inflammation site by regulating chemokine release.
• Form: Lyophilized
• Bio-activity: Measure by its ability to induce cytotoxicity in L929 cells in the presence of actinomycin D. The ED50 for this effect is < 40 pg/mL. The specific activity of recombinant mouse TNF alpha is approximately >2.5 × 10⁷ IU/mg.
• Molecular Mass: The protein has a calculated MW of 18.2 kDa.
  The protein migrates as 16 kDa under reducing condition (SDS-PAGE analysis).
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >98% as determined by SDS-PAGE analysis.
• Storage: This product is stable after storage at:
  -20 centigrade for 12 months in lyophilized state from date of receipt.
  -20 or -80 centigrade for 1 month under sterile conditions after reconstitution.
  Avoid repeated freeze/thaw cycles.
• Storage Buffer: Lyophilized from a 0.2 μm filtered solution of PBS, pH 8.0.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
• Shipping: The product is shipped with polar packs. Upon receipt, store it immediately at -20 centigrade or lower for long term storage.
