Cat#:RP-3986H;Product Name:Recombinant Human IFNW1 Protein;Synonym:Interferon omega-1, Interferon alpha-II-1, IFNW1.;Description:Interferon-Omega 1 Protein produced in E.coli is a single, non-glycosylated, polypeptide chain containing 172 amino acids and having a molecular mass of 19.9kDa. The Interferon-Omega 1 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:MCDLPQNHGL LSRNTLVLLH QMRRISPFLC LKDRRDFRFP QEMVKGSQLQ KAHVMSVLHE MLQQIFSLFH TERSSAAWNM TLLDQLHTGL HQQLQHLETC LLQVVGEGES AGAISSPALT LRRYFQGIRV YLKEKKYSDC AWEVVRMEIM KSLFLSTNMQ ERLRSKDRDL GSS.;Purity:Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:The ED50 was determined by a cytotoxicity assay using Human TF-1 cells is < 0.01 ng/ml, corresponding to a specific activity of > 100,000,000 units/mg.;Formulation:Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized IFNW1 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized IFNW1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFNW1 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.;
