Active Recombinant Human IFNB1

• Cat.No.: IFNB1-533H
• Product Overview: Recombinant Human IFNB1 produced in E. coli is approximately 20.0 kDa, a single non-glycosylated polypeptide chain containing 166 amino acids.

Specification

• Description: IFN-βs are proteins produced by many cell types including lymphocytes (NK cells, B-cells and T-cells), macrophages, fibroblasts, endothelial cells, osteoblasts and others. They have antiviral activity that it is mainly involved in innate immune response. The IFN-β family has 2 subtypes,which are IFN-β1 (IFNB1) and IFN-β3 (IFNB3) (a gene designated IFN-β2 is actually IL-6). IFN-β1 is used as a treatment for multiple sclerosis as it reduces the relapse rate.
• Source: E. coli
• Species: Human
• Form: Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4, containing 2% HSA and 3% mannitol.
• Bio-activity: Fully biologically active when compared to standard. The specific activity determined by an anti-viral assay is no less than 3.2 × 10^7IU/mg.
• Molecular Mass: 20 kDa

• Endotoxin: Less than 1EU/μg of rHuIFN-β1b as determined by LAL method.
• Purity: >97% by SDS-PAGE and HPLC analyses.
• Usage: This material is for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
• Storage: This lyophilized preparation is stable at 2-8 centigrade, but should be kept at -20 centigrade for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 centigrade. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 centigrade to -70 centigrade. Avoid repeated freeze/thaw cycles.
• Reconstitution: We recommend that this vial be briefy centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 centigrade. Further dilutions should be made in appropriate buffered solutions.
