Description
Recombinant Human Interferon alpha-2a is produced by our E.coli expression system and the target gene encoding Cys24-Glu188 is expressed.
Alias
Interferon Alpha-2; IFN-Alpha-2; Interferon Alpha-A; LeIF A; IFNA2
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Activity
Measured by a viral resistance assay using VSV-WISH cells.The ED50 for this effect is typically 10 pg/mL.
Formulation
Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2.
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 3 months.
Warranty
For Research Use Only. Our recombinant proteins can not be used in diagnostic procedures.
