    复溶
    • Always centrifuge tubes before opening.Do not mix by vortex or pipetting.
    • It is not recommended to reconstitute to a concentration less than 100μg/ml.
    • Dissolve the lyophilized protein in distilled water.
    • Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 
     
    运输条件
    • The product is shipped at ambient temperature.
    • Upon receipt, store it immediately at the temperature listed below.
     
    保存条件
    • Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt.
    • Reconstituted protein solution can be stored at 2-8°C for 2-7 days.
    • Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
     
    产品背景
    At least 23 different variants of IFN-α 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-α subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-α 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.
