85-1576-30 ［取扱停止］Interferon alpha 2 (alpha 2b), Recombinant, Human (Interferon alpha-2, IFN-alpha-2, IFNa2, IFNa2b, Interferon alpha-A, IFN-alphaA, IFNA, LeIF A, MGC125764, MGC125765) 20ug I7661-75C
特徴
- Recombinant protein corresponding to 166aa of human Interferon-alpha 2b expressed in E. coli is a single, non-glycosylated, polypeptide chain.
- Biological Activity:The specific activity as determined in a viral resistance assay using bovine kidney MDBK cells was found to be 2.6x10e8 IU/mg.
- Protein Content:Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280nm using the absorbency value of 0.924 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of Recombinant corresponding to Interferon-alpha 2b as a Reference Standard.
