概述 形态 Lyophilized from a 0.2 μm filtered concentrated solution in sodium citrate buffer (1 liter of ddH2O containing 5.9 g of sodium citrate, 5.8 g of sodium chloride and 0.06 g of citric acid). 来源 CHO 氨基酸序列 APPRLICDSR VLERYLLEAK EAENITTGCA EHCSLNENIT VPDTKVNFYA WKRMEVGA VEVWQGLALL SEAVLRGQAL LVNSSQPWEP LQLHVDKAVS GLRSLTTLLR ALGAQKEAIS PPDAASAAPL RTITADTFRK LFRVYSNFLR GKLKLYTGEA CRTGDR 内毒素水平 Less than 0.01 EU/μg of Recombinant HumanEPO-α as determined by LAL method. 活性 Fully biologically active when compared to standard. The Specific Activity was measured by the stimulation of reticulocyte production in normocyth-aemic mice and is no less than 1.5 × 105 IU/mg. Accession # P01588 预期分子量 Mature human EPO, containing 166 amino acid residues, has a predicted molecular mass of approximay 21 kDa. As a result of glycosylation, the recombinant protein migrates with an apparent molecular mass of 36-40 kDa in SDS-PAGE. 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 > 98 % by SDS-PAGE and HPLC analyses. Gene IDs 2056 参考文献 1. Hanicki Z. 1988. Pol Arch Med Wewn, 80: 290-3.<br/>2. Haniu M, Narhi LO, Arakawa T, et al. 1993.
