Recombinant Human Interferon, Beta 1, Fibroblast

• Cat.No.: IFNB1-19H
• Product Overview: Recombinant Human Interferon-beta 1a produced inCHO (Chinese Hamster Ovarian) cellsis 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.

Specification

• Species: Human
• Source: CHO
• Tag: Non
• Description: Interferon-beta 1b has antiviral, antibacterial and anticancer activities.
• 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.
• Physical Appearance: Lyophilized from 1mg/ml solution containing 91 mg Human Albumin, and 620mg mannitol, and 9 mg Sodium Acetate.
• Purity: Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
• Formulation: Lyophilized from a concentrated 1mg/ml solution containing PBS 7.4.
• 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.
• 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.
• Storage: Lyophilized Interferon-beta 1a although stable at room temperature for 3 weeks, should be stored desiccated below -18℃. Upon reconstitution IFN-Beta1a should be stored at 4℃ between 2-7 days and for future use below -18℃.Please prevent freeze-thaw cycles.
