Description: Tumor Necrosis Factor-b Human Recombinant (Lymphotoxin) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 172 amino acids and having a molecular mass of 18645 Dalton. The TNF-b is purified by standard chromatographic techniques. Uniprot Accesion Number: P01374 Amino Acid Sequence:MLPGVGLTPS AAQTARQHPK MHLAHSTLKP AAHLIGDPSK QNSLLWRANT DRAFLQDGFS LSNNSLLVPT SGIYFVYSQV VFSGKAYSPK ATSSPLYLAH EVQLFSSQYP FHVPLLSSQK MVYPGLQEPW LHSMYHGAAF QLTQGDQLST HTDGIPHLVL SPSTVFFGAF AL. Source: Escherichia Coli. Physical Appearance and Stability: Lyophilized Tumor Necrosis Factor-b although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution TNF-b should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. Formulation and Purity: Lyophilized protein with no additives. Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAG. Application: Solubility: It is recommended to reconstitute the lyophilized Tumor Necrosis Factor-beta in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: The ED50 as determined by the cytolysis of murine L929 cells in the presence of Actinomycin D is < 0.05ng/ml, corresponding to a Specific Activity of 20, 000, 000IU/mg. Shipping Format and Condition: Lyophilized powder at room temperature. Usage Statement: Our products are furnished for LABORATORY RESEARCH USE ONLY.
