Source Optimized DNA sequence encoding Human Interferon alpha-2b mature chain was expressed in Escherichia Coli.
Molecular weight Native human IFNa-2b is generated by the proteolytic removal of the signal peptide and propeptide, the molecule has a calculated molecular mass of approximately 19 kDa. Recombinant Interferon-alpha 2b is a monomeric protein consisting of 166 amino acid residue subunits.Interefron alpha 2b migrates as an approximately 19 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE.
Purity >98%, as determined by SDS-PAGE and HPLC
Biological Activity The ED(50) was determined by viral resistance assayand was found to benot less than5x108IU/mg.

Endotoxin Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than.1 ng/µg(1EU/µg).
Presentation IFN-alpha2b was lyophilized from a.2 μm filtered PBS solution pH7.0.
Reconstitution A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than.1 mg/mL. This solution can then be diluted into other buffers.
Storage The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at° -° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
Usage This cytokine product is for research purposes only.It may not be used for therapeutics or diagnostic purposes.
