Desription Interferon-a 2b Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 166 amino acids and having a molecular mass of 19400 Dalton.The Interferon-alpha 2b gene was obtained from human leukocytes.The IFN-a 2b is purified by proprietary chromatographic techniques.

Source Escherichia Coli.

Appearance Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation Lyophilized from a (1 mg/ml) solution in containing 2.3 mg Sodium phosphate dibasic and 0.55 mg sodium phosphate monobasic buffer.

Solubility It is recommended to reconstitute the lyophilized Interferon-alpha 2b in sterile 18MΩ-cm H2O not less than 100g/ml, which can then be further diluted to other aqueous solutions.

Stability Lyophilized Interferon although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution IFN alpha 2b should be stored at 4C between 2-7 days and for future use below -18C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Purity >98.0% as determined by RP-HPLC and SDS-PAGE.

Amino acid sequence The sequence of the first five N-terminal amino acids was determined and was found to be Met-Cys-Asp-Leu-Pro.

Activity The specific activity as determined in a viral resistance assay using bovine kidney MDBK cells was found to be 260,000,000 IU/ mg.

Usage For LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
