- Recombinant Human IFN-β1b
概述 种属 Human 形态 Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4, containing 2 % HSA and 3 % mannitol. 来源 Escherichia coli. 氨基酸序列 MSYNLLGFLQ RSSNFQCQKL LWQLNGRLEY CLKDRMNFDI PEEIKQLF QKEDAALTIY EMLQNIFAIF RQDSSSTGWN ETIVENLLAN VYHQINHLKT VLEEKLEKED FTRGKLMSSL HLKRYYGRIL HYLKAKEYSH CAWTIVRVEI LRNFYFINRL TGYLRN 内毒素水平 Less than 1 EU/µg of Recombinant HumanIFN-β1b as determined by LAL method. 活性 Fully biologically active when compared to standard. The specific activity determined by an anti-viral assay is no less than 3.0 × 107 IU/mg. Accession # P01574 预期分子量 Approximay 20.0 kDa, a single non-glycosylated polypeptide chain containing 166 amino acids. 性能 溶解方法 We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. 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 °C. Further dilutions should be made in appropriate buffered solutions. 保存方法 This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles. 纯度 > 97 % by SDS-PAGE and HPLC analyses. Gene IDs 3456 参考文献 1. Yoshino A, Tashiro S, Ogino A, et al. 2011. Int J Oncol, 39: 529-42.<br/>2.
