Product Description
Recombinant Human Interferon-Beta- 1b 10ug
Description - Interferon beta 1b Human Recombinant produced in
E.Coli is a single, non-glycosylated mutein (variant form)
of human Interferon beta-1b polypeptide chain containing 165 amino
acids and having a molecular mass of 18510.86 Dalton. The IFN-beta
gene was cloned from human fibroblasts and altered to substitute
Serine for the Cysteine residue found at position 17.
IFN beta-1b is purified by proprietary chromatographic techniques.
Appearance - Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation - Lyophilized from 1mg/ml solution containing 50mg Human Albumin & 50mg dextrose
Solubility - It is recommended to reconstitute the lyophilized Interferon
beta-1b in sterile 18MΩ-cm H2O not less than 100µg/ml, which can
then be further diluted to other aqueous solutions.
Stabilty - Lyophilized Interferon beta-1b although stable at room
temperature for 3 weeks, should be stored desiccated below -18 C.
Upon reconstitution,liquid form of IFNB 1b should be stored at 4 C up
to 3 weeks 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.
