Product Name Interferon-Beta 1b Human Recombinant
Synonyms Leukocyte interferon, B cell interferon, Type I interferon, IFNB1, IFB, IFF, IFNB, IFN-b 1b, MGC96956.
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.
Uniprot Accesion Number P01574
Amino Acid SequenceThe sequence of the first five N-terminal amino acids was determined and was found to be Ser-Tyr-Asn-Leu-Leu.
Source Escherichia Coli.
Physical Appearance and Stability Lyophilized Interferon-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.
Formulation and Purity Lyophilized from 1mg/ml solution containing 50mg Human Albumin & 50mg dextrose. Greater than 98.0% as determined by
Application
Solubility It is recommended to reconstitute the lyophilized Interferon beta-1b in sterile 18M-cm H2O at a concentration of 0.25mg/ml, which can then be further diluted to other aqueous solutions.
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.
Shipping Format and Condition Lyophilized powder at room temperature.
