Storage Conditions	This lyophilized preparation is stable at 2-4C, but should be kept at -20C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-4C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20C to -80C. Avoid repeated freeze/thaw cycles.
Molecular Weight	19.5 kDa
Description	At least 23 different variants of IFN-alpha 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-alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end.
Formulation	Lyophilized from a 0.2 um filtered solution in PBS, pH 7.4, + 4% mannitol and 1% HSA.
Reconstitution	Centrifuge vial prior to opening. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20C. Further dilutions should be made in appropriate buffered solutions.
Specificity	1 x 108 IU/ mg
Biological Activity	The specific activity as determined in a viral resistance assay was found to be no less than 1 x 108 IU/mg.
Endotoxin Level	<1 EU/ug recombinant protein as determined by LAL method.
