Recombinant Human IFN alpha2b Protein

Molecular weight: 19.4 KDaDescription: Recombinant Human Interferon Alpha-2b is produced by our E.coli and the target gene encoding Cys24-Glu188 (Lys46Arg) is expressed.At least 23 different variants of IFN-a 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-a subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-a subtypes differ in their sequences by only one or two positions. Naturally occurring variants also include proteins that are truncated by 10 amino acids at the carboxyl-terminal end.
