Product name | Recombinant Mouse TNF-alpha Protein |
---|---|
Catalog No. | RP01071 |
Description | Recombinant Mouse TNF-alpha Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Leu80-Leu235) of mouse TNF-alpha (Accession #NP_038721.1) fused with a 6×His tag at the C-terminus. |
Bio-Activity |
1.Recombinant Mouse TNF-α protein was measured by NF-κB reporter assay in HEK293 cells. The ED50 for this effect is 40-200 pg/mL. 2.Measured by its binding ability in a functional ELISA. Immobilized Mouse TNF-α at 2 μg/mL (100 μL/well) can bind Mouse TNFRSF1B with a linear range of 0.02-0.77 ng/mL. 3.Measured in a cytotoxicity assay using L-929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is 0.025-0.1 pg/mL. |
Purity | > 87% by SDS-PAGE. |
Endotoxin | < 0.1 EU/μg of the protein by LAL method. |
Formulation | Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation. |
Species | Mouse |
Storage | Store the lyophilized protein at -20°C to -80 °C for long term. After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week. |
---|---|
Reconstitution | Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. |
