保存 Lyophilized Protein should be stored at < -20℃, though stable at room temperature for 3 weeks. Reconstituted Protein solution can be stored at 4-7℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.
运输 The product is shipped at ambient temperature.Upon receipt, store it immediately at the temperature listed below.
制剂 Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2.
复融 Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in distilled water Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

背景介绍

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 only differ in their sequences by one or two positions. Naturally occurring variants also include Proteins truncated by 10 amino acids at the carboxy-terminal end.
