Alias	protein/Z02866-Interferon-alpha_1b_IFN-alpha1b_Human, 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.</td></tr><tr><th>M.W.</th><td colspan="7"> Approximately 19.5 kDa, a single non-glycosylated polypeptide chain containing 167 amino acids.</td></tr><tr><th>Purity</th><td colspan="7"> >96% by SDS-PAGE and HPLC analyses.</td></tr><tr><th>Endotoxin Level</th><td colspan="7"> Less than 0.2EU/ug of rHuIFNalpha1b as determined by LAL method.</td></tr><tr><th>Specific Activity</th><td colspan="7"> Fully biologically active when compared to standard. The specific activity as determined in a viral resistance assay was found to be no less than 1.0 x 108 IU/mg.</td></tr><tr><th>Storage</th><td colspan="7"> This lyophilized preparation is stable at 2-8 C, but should be kept at -20 C for long term storage, preferably desiccated.
