Interferon-alpha 2b Human Recombinant produced in yeast is a single, glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of approximately 19.3 kDa.
The IFN-a 2b is purified by proprietary chromatographic techniques.
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH-7.4 and 0.02% Tween-20.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
(b) Analysis by SDS-PAGE.
