Recombinant Human IFNα2b 500ug

Known as	Interferon Alpha-2; IFN-Alpha-2; Interferon Alpha-A; LeIF A; IFNA2
Derived from	E.coli
Purity	Measured by a viral resistance assay using VSV-WISH cells.Specific Activity is greater than 1.0 x 10^8 IU/ mg.Greater than 95% as determined by reducing SDS-PAGE.
Formulation	Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2.
Shipping	The product is shipped at ambient temperature.Upon receipt, store it immediately at the temperature listed below.
Storage	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 14 months
Reconstitution	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 in12X PBS.Please aliquot the reconstituted solution to minimize freeze-t cycles.
Endotoxin	Less than 0.1 ng/ug (1 IEU/ug).

Background	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.
