GMP Recombinant Human TNF

Cat.No.: TNF-4342HG
Product Overview: Recombinant Human TNF was produced in E. coli using non-animal reagents in an animal-free facility under cGMP guidelines.
Description: Tumor necrosis factor a (TNF-a;), also called cachectin, is produced by neutrophils, activated lymphocytes, macrophages, NK cells, LAK cells, astrocytes endothelial cells, smooth muscle cells and some transformed cells. TNF-a; occurs as a secreted, soluble form and as a membrane-anchored form, both of which are biologically active. The naturally-occurring form of TNF-a; is glycosylated, but non-glycosylated recombinant TNF-a; has comparable biological activity. The biologically active native form of TNF-a; is reportedly a trimer. Human and murine TNF-a; show approximately 79% homology at the amino acid level and crossreactivity between the two species. Two types of receptors for TNF-a; have been described and virtually all cell types studied show the presence of one or both of these receptor types.
Source: E. coli
Species: Human
Form: Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, 10 mM NaCl, pH 7.0.
Bio-activity: The ED50 determined by a cytotoxicity assay using murine L929 cells is less than 0.05 ng/mL, corresponding to a specific activity of >2.0 × 10^7 IU/mg in the presence of actinomycin D.
Molecular Mass: Approximately 17.5 kDa, a single non-glycosylated polypeptide chain containing 158 amino acids.
AA Sequence: MVRSSSRTPSDKPVAHVVANPQAEGQLQWLNRRANALLANGVELRDNQLVVPSEGLYLIYSQVLFKGQGCPSTHVLLTHTISRIAVSYQTKVNLLSAIKSPCQRETPEGAEAKPWYEPIYLGGVFQLEKGDRLSAEINRPDYLDFAESGQVYFGIIAL
Endotoxin: Less than 1 EU/μg of the protein by LAL method.
Purity: >98% by SDS-PAGE and HPLC analyses.
Storage: This lyophilized preparation is stable at 2-8 centigrade, but should be kept at -20 centigrade for long term storage, preferably des centigradecated. Upon reconsitution, the preparation is stable for up to one week at 2-8 centigrade. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 centigrade to -70 centigrade. Avoid repeated freeze/thaw centigrade centigradeles.
Reconstitution: Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 centigrade. Further dilutions should be made in appropriate buffered solutions.
Quality Statement: Our GMP proteins are produced according to relevant sections of the following documents: WHO TRS, No. 822, 1992 Annex 1, Good Manufacturing Practices for Biological Products; USP Chapter 1043, Ancillary Materials for Cell, Gene and Tissue-Engineered Products and USP Chapter 92, Growth Factors and Cytokines Used in Cell Therapy Manufacturing.
Shipping: The product is shipped at ambient temperature. Upon receipt, store it immediately at the recommended temperature.
