Interferon Alpha-2; IFN-Alpha-2; Interferon Alpha-A; LeIF A; IFNA2 Description - Recombinant Mouse Interferon Alpha-2 is produced by our E.coli expression system and the target gene encoding Cys24-Glu190 is expressed. Calculated Molecular Weight - Mol Mass:19.5 KDa; APMol Mass:16 KDa, reducing conditions Formulation - Lyophilized from a 0.2 μm filtered solution of 20mM Histidine-HCl, 6% Sucrose, 4% Mannitol, 0.02% Tween80 (w/v), pH 6.0. Endotoxin - < 1 EU/µg as determined by LAL test. 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 in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. Shipping - The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below. Background - At least 23 different variants of Interferon-α are known. The individual proteins have molecular masses between 19-26 kD 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 at only one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxyl-terminal end.
