产品描述 Description
产品文档 Product Documents
Purity:>98%
Product Data
Purity
Greater than 96.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Shipping Condition
Shipped at Room temp.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Cys-Asp-Leu-Pro-Glu.
Solubility
It is recommended to reconstitute the lyophilized IFN alpha 1b in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized Interferon alpha 1b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution IFN-alpha 1b should be stored at 4°C between 2-7 days and for future use below -18°C .For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Biological Activity
The specific activity as determined in a viral resistance assay using bovine kidney MDBK cells was found to be 1 x 108 IU/ mg.
Formulation
Lyophilized from a 0.2µm filtered solution (50ug/ml) in PBS, pH 7.4, containing 4% mannitol and 1% HSA.
