Product Description
Recombinant Human Interferon-alpha 2a 20ug
Description - Interferon Alpha Human 2a Recombinant produced in
E.Coli is a single, non-glycosylated, polypeptide chain containing
165 amino acids and having a molecular mass of 19241 Dalton.
The Interferon-α 2a gene was obtained from human leukocytes.
The IFN-A 2a is purified by proprietary chromatographic techniques.
Physical Appearance - Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation - Lyophilized from (1mg/ml) solution containing 7.21
sodium chloride and 0.77 mg ammonium acetate.
Solubility - It is recommended to reconstitute the lyophilized Interferon-alpha
2a in sterile 18MΩ-cm H2O not less than 100µg/ml,
which can then be further diluted to other aqueous solutions.
Stability - Lyophilized Interferon alpha 2a although stable at room
temperature for 3 weeks, should be stored desiccated below -18°C.
Upon reconstitution IFN-alpha 2a 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.
