Recombinant of human IFN a 1b protein
Product Specifications
Source
Escherichia Coli
Field of Research
Infectious Disease & Virology
Purity
Greater than 96.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Bioactivity
The specific activity as determined in a viral resistance assay using bovine kidney MDBK cells was found to be 1 x 108 IU/ mg.
Form
Sterile Filtered White lyophilized (freeze-dried) powder.
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.
Storage Conditions
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
Notes
For research use only.
Applications Notes
Cytokines And Growth Factors
Preservative
Lyophilized from a 0.2μm filtered solution (50ug/ml) in PBS, pH 7.4, containing 4% mannitol and 1% HSA.
AA Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Cys-Asp-Leu-Pro-Glu
