Product Name:Human IFN b 1b Recombinant Protein
Product Code:RPPB0394
Size:10µg
Species:Human
Target:IFN b 1b
Synonyms:Leukocyte IFN, B cell IFN, Type I IFN, IFNB1, IFB, IFF, IFNB, IFN-b 1b, MGC96956.
Source:Escherichia Coli
Physical 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 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:Greater than 98.0% as determined by:(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Amino Acid Sequence:The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Tyr-Asn-Leu-Leu
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 32 x 106 IU/mg.

IFN-beta 1b has antiviral, antibacterial and anticancer activities.

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.

UniProt Protein Function:IFNB1: Has antiviral, antibacterial and anticancer activities. Belongs to the alpha/beta interferon family.
