  • 状态
    Lyophilized
    溶解方式
    It is not recommended to reconstitute to a concentration less than 100 μg/mL.
    Dissolve the lyophilized protein in ddH2O.
    Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
    缓冲液
    Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.2.
    注意事项
    Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
    储存条件
    4 °C/-20 °C/-80 °C
    储存方法
    Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
    Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
    Aliquots of reconstituted samples are stable at < -20°C for 3 months.

    背景
    At least 23 different variants of IFN-alpha are known. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences by only one or two positions. Naturally occurring variants also include proteins that are truncated by 10 amino acids at the carboxyl-terminal end.
