Recombinant Murine Tumor Necrosis Factor

• Cat.No.: Tnf-331M
• Product Overview: Recombinant Murine Tumor Necrosis Factor-alpha (rMu TNF-alpha) is a pleiotrophic proinflammatory cytokine secreted by various cells including adipocytes, activated monocytes, macrophages, B cells, T cells and fibroblasts expressed inSteptomyces lividans. MW=17.3kDa.

Specification

• Species: Mouse
• Source: Steptomyces lividans
• Tag: Non
• Description: TNF-alpha is cytotoxic to a wide variety of tumor cells and is an essential factor in mediating the immune response against bacterial infections. TNF-alpha also plays a role in the induction of septic shock, auto immune diseases, rheumatoid arthritis, inflammation, and diabetes. Recombinant murine TNF-alpha is a soluble 156 amino acid protein which corresponds to C-terminal extracellular domain of the full length transmembrane protein.
• Quantity: 20 μg.
• Specific Activity: ≥ 9 x 10⁸ IU/mg.
• Purity: Greater than 98% (determined by SDS-PAGE and HPLC analysis).
• Endotoxin Level: < 0.1 ng per μg of rMu TNF-alpha (1EU/μg).
• Biological Activity: Recombinant human TNF-alpha is fully biologically active when compared to a standard. The ED₅₀, as determined by the cytolysis of murine L929 cells in the presence of actinomycin D, is 0.05 ng/ml corresponding to a specific activity of ≥ 9 x 10⁸ units/mg.
• Formulation: Sterile, lyophilized protein. Each mg contains 50 mM Tris-HCl (pH 8.0) and 20 mM NaCl.
• Reconstitution: Please note: Always centrifuge product briefly before opening the vial. The lyophilized rMu TNFalpha should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can then be further diluted into other aqueous buffers and stored at -20°C for future use.
• Storage And Stability: The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rMu TNF-alpha protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
