Leukocyte IFN, B cell IFN, Type I IFN, IFNB1, IFB, IFF, IFNB, IFN-b 1b, MGC96956.
INTRODUCTION
IFN-beta 1b has antiviral, antibacterial and anticancer activities.
DESCRIPTION
IFN beta 1b Human Recombinant produced in E.Coli is a single, non-glycosylated mutein (variant form) of human IFN 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.

PHYSICAL APPEARANCE
FORMULATION
SOLUBILITY
It is recommended to reconstitute the lyophilized IFN beta-1b in sterile 18M-cm H2O at a concentration of 0.25mg/ml, which can then be further diluted to other aqueous solutions.
STABILITY
Lyophilized IFN-beta 1b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IFNB 1b should be stored at 4°C between 2-7 days and for future use below -18°C.
Please prevent freeze-thaw cycles.
PURITY
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
AMINO ACID SEQUENCE
BIOLOGICAL ACTIVITY
PROTEIN CONTENT
1. UV spectroscopy at 280 nm using the absorbency value of 1.493 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of IFN-beta as a Reference Standard.
