Description Interferon-alpha 1b Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 166 amino acids and having a molecular mass of 19392 Dalton.The Interferon-alpha 1b gene was obtained from human leukocytes.The IFN-a 1b is purified by proprietary chromatographic techniques.
Uniprot Accesion Number Q8WZ68
Amino Acid SequenceThe sequence of the first five N-terminal amino acids was determined and was found to be Cys-Asp-Leu-Pro-Glu.
Source Escherichia Coli.
Physical Appearance and 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.
Formulation and Purity Lyophilized from a 0.2µm filtered solution (50ug/ml) in PBS, pH 7.4, containing 4% mannitol and 1% HSA. Greater than 96.0% as determined by
Application
Solubility It is recommended to reconstitute the lyophilized IFN alpha 1b in sterile 18MO-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
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.
Shipping Format and Condition Lyophilized powder at room temperature.
