Product Description
Recombinant Human Interferon-Beta- 1a 2ug
Description - Interferon-beta 1a Human Recombinant produced
in CHO (Chinese Hamster Ovarian) cells is a single, glycosylated
polypeptide chain containing 166 amino acids and having
a molecular mass of 22500 Dalton.
IFN-beta1a is purified by proprietary chromatographic techniques
Appearence - Sterile Filtered White lyophilized (freeze-dried) powder
Formulation - Lyophilized from 1mg/ml solution containing 91 mg Human
Albumin, and 620 mg mannitol, and 9 mg Sodium Acetate.
Solubility - It is recommended to reconstitute the lyophilized Interferon
beta-1a in sterile 18MΩ-cm H2O not less than 100µg/ml, which
can then be further diluted to other aqueous solutions.
Stability - Lyophilized Interferon-beta 1a although stable at room
temperature for 3 weeks, should be stored desiccated below -18°C.
Upon reconstitution IFN-beta-1a 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).
Purity - Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Please avoid freeze-thaw cycles.
