Specifications and Use

Description:

Recombinant human IFN a-2a produced in Yeast is a single, non-glycosylated, polypeptide chain containing 165 amino acids, two pairs of disulfide bonds and having a molecular mass of approximately 19.2kD.

Source: Yeast.

Molecular Mass: Approximately 19.2kD.

Purity: ≥97%.

Endotoxin Level: <1EU/µg, determined by the LAL method.

Biological Activity:

Bioactivity is detected using cytopathic effect inhibition assay method, MDBK cell (Madin-Darby bovine kidney) as dependent cell strain. The specific activity shall be not less than 2.0×108 IU/mg.

Formulation:

Lyophilized from a 0.2μm filtered solution in 20mM Phosphate buffer.

Reconstitution:

It is recommended to centrifuge at 10,000rpm for 30-60 sec or 3000rpm for 5 min before opening the tube, and then reconstitute with 0.2ml sterile water.

Storage:

  • Lyophilized samples are stable for 36 months from date of manufacture at -20℃ to -70℃.

  • Upon reconstitution, this cytokine can be stored under sterile conditions at 2- 8℃ for one month or at -20℃ to -70℃ in a manual defrost freezer for three months without detectable loss of activity.

  • Avoid repeated freeze-thaw cycles.
