Product Description
Recombinant Human Interferon-alpha 2b 20ug
Description - Interferon-α 2b Human Recombinant produced in E.Coli
is a single, non-glycosylated, polypeptide chain containing 165
amino acids and having a molecular mass of 19269 Dalton.
The Interferon-alpha 2b gene was obtained from human leukocytes.
The IFN-α 2b is purified by proprietary chromatographic techniques.
Appearance - Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation - Lyophilized from a (1 mg/ml) solution in containing2.3 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 18MO-cm H2O not less than 100µg/ml,
which can then be further diluted to other aqueous solutions.
Stability - Lyophilized Interferon-alpha 2b although stable at room
temperature for 3 weeks, should be stored desiccated below -18°C.
Upon reconstitution IFN alpha 2b 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 avoid freeze-thaw cycles.
Purity - Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
