Gene IDs: 3456
纯度: > 97 % by SDS-PAGE and HPLC analyses.
来源: Escherichia coli.
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.
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.
形态: Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4, containing 2 % HSA and 3 % mannitol.
储存/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.
