- 溶解方式
- It is recommended to reconstitute the lyophilized Recombinant Human Interferon alpha 2a (IFN alpha 2a) in sterile 18 M-omega-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. Quantitation Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm using the absorbency value of 0.924 as the extinction coefficient for a 0.1% (1 mg/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 IFN-alpha 2a as a Reference Standard.

- 背景
- Human Interferon alpha 2a (IFN alpha 2a) produced in E. coli is a single, non-glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of 19,241 Da. The Interferon alpha 2a (IFN alpha 2a) gene was obtained from human leukocytes. The Recombinant Human Interferon alpha 2a (IFN alpha 2a) is purified by proprietary chromatographic techniques. Synonym: rHuIFN-alpha 2a, rHuIFNalpha 2a, rHuIFN-a 2a, rHuIFN-alfa 2a, rHuIFNalfa 2a, Interferon-alpha 2a, Interferonalpha 2a, Interferon-a 2a, Interferon-alfa 2a, Interferonalfa 2. Formulation: Lyophilized from (1 mg/ml) solution containing 7.21 sodium chloride and 0.77 mg ammonium acetate.
