Description of Human IFN-beta 1a (glycosylated)
IFN-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.
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.
Reconstitution
It is recommended to reconstitute the lyophilized IFN beta 1a in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized IFN-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 avoid repeated freeze-thaw cycles.
