• Category: Proteins
• Description: Recombinant Human Tumor necrosis factor protein
• Tag: N-terminal 6xHis-tagged
• Form/Appearance: Lyophilized powder
• Buffer/Preservatives: Lyophilized from 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0
• Purity: Greater than 90% as determined by SDS-PAGE.
• Protein Sequence: VRSSSRTPSDKPVAHVVANPQAEGQLQWLNRRANALLANGVELRDNQLVVPSEGLYLIYSQVLFKGQGCPSTHVLLTHTISRIAVSYQTKVNLLSAIKSPCQRETPEGAEAKPWYEPIYLGGVFQLEKGDRLSAEINRPDYLDFAESGQVYFGIIAL
• Protein Length: Partial
• UniProt ID: P01375
• MW: 19.4 kDa
• Application notes: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
• Endotoxins: Not test.
• Source: Yeast
• Biological Origin: Homo sapiens (Human)
• Biological Activity: Measured by its binding ability in a functional ELISA. Immobilized Human TNF at 5 μg/mL can bind Human TNFR2 protein (CSB-MP023978HU2). The EC50 is 3.470-4.107 ng/mL.
• Expression Region: 77-233aa
• Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
• Alternative names: Cachectin TNF-alpha Tumor necrosis factor ligand s
