Détail du produit

Séquence: analysis The sequence of the first five N-terminal amino acids was determined and was found to be Met-Cys-Asp-Leu-Pro, conforming to the sequence of native human IFN-alpha. N-terminal methionine has been completely removed enzymatica lly. p to grams level.

Attributs du produit: The specific activity as determined in a viral resistance assay using VSV-WISH cells was found to be greater than 1.0 x 108 IU/ mg.

niveau d'endotoxine: Level Less than 0.1 ng/µg (IEU/µg) of recombinant human Interferon alpha 2a (IFN alpha 2a

Information d'application

Restrictions: For Research Use only

Stockage

Format: Lyophilized

Reconstitution: 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.
