Recombinant Human IFNA2 protein

• Cat.No.: IFNA2-03H
• Product Overview: Recombinant Human IFNA2 alpha 2b protein was expressed in Escherichia coli.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Protein Length: 166
• Description: IFN-αs are proteins secreted by leukocyte. They are mainly involved in innate immune response against viral infection. The IFN-α family has 13 subtypes and 23 different variants. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN-α subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN-alpha subtypes differ in their sequences at only one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end.
• Form: Lyophilized from a 0.2μm filtered solution in PBS, pH 7.4.
• Bio-activity: Fully biologically active when compared to standard. The specific activity determined by an anti-viral assay is no less than 1.0 × 10⁸ IU/mg.
• Molecular Mass: Approximately 19.4 kDa, a single non-glycosylated polypeptide chain containing 166 amino acids.

• Endotoxin: Less than 1 EU/µg of rHuIFN-α2b, Ecoli. as determined by LAL method.
• Purity: >96% by SDS-PAGE and HPLC analysis.
• Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
• Reconstitution: We recommend that this vial be briefly 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.
