Product Name: 4-1BB Ligand Human Recombinant Synonyms: CD137L, CD137-L, 4-1BBL, 4-1BB Ligand, TNFSF9, Tumor Necrosis Factor (ligand) Superfamily Member 9. Description: 4 1BBL Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 184 amino acids and having a molecular mass of 19.5kDa.The 4 1BBL is purified by proprietary chromatographic techniques. Uniprot Accesion Number: P41273 Amino Acid Sequence:REGPELSPDD PAGLLDLRQG MFAQLVAQNV LLIDGPLSWY SDPGLAGVSL TGGLSYKEDT KELVVAKAGV YYVFFQLELR RVVAGEGSGS VSLALHLQPL RSAAGAAALA LTVDLPPASS EARNSAFGFQ GRLLHLSAGQ RLGVHLHTEA RARHAWQLTQ GATVLGLFRV TPEIPAGLPS PRSE Source: Escherichia Coli. Physical Appearance and Stability: Lyophilized 4 1BBL although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution 4 1BBL should be stored at 4C between 2-7 days and for future use below -18C.Please prevent freeze-thaw cycles. Formulation and Purity: Lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4. Greater than 95.0% as determined by SDS-PAGE. Application: Solubility: It is recommended to reconstitute the lyophilized 4 1BBL in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Biological Activity: Fully biologically active when compared to standard. Determined by the dose-dependent stimulation of IL-8 production by human PBMC. The ED50 for this effect is 5-10ng/ml corresponding to a Specific Activity of 100, 000-200, 000IU/mg. Shipping Format and Condition: Lyophilized powder at room temperature. Usage Statement: Our products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
