INTRODUCTION
Interferon-beta has antiviral, antibacterial and anticancer activities.
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.
SOURCE
CHO (Chinese Hamster Ovarian) cells.
FORMULATION
Lyophilized from a solution (1mg/3.4ml) containing 91 mg Human Albumin, and 620 mg mannitol and 50mM Acetate acid pH 3.8.
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-Beta1a should be stored at 4°C between 2-7 days and for future use below -18°C.
Please prevent freeze-thaw cycles.
PURITY
Greater than 99.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
BIOLOGICAL ACTIVITY
The specific activity as determined in a viral resistance assay (human "Wish" cell line and VSV virus or the monkey VERO cell line with EMCV virus) was found to be 270 x 106 IU/mg.
USAGE
ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
