Specifications and Use

Description:

Recombinant human IL-2 produced in Yeast is a single, non-glycosylated, polypeptide chain containing 133 amino acids, one pair of disulfide bond and with 125 cys. aa. mutated to Ala aa, having a molecular mass of approximately 15.4kD.

Source: Yeast.

Molecular Mass: Approximately 15.4kD.

Purity: ≥97%.

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

Biological Activity:

Measured in a cell proliferation assay using an IL-2 dependent Mouse cytotoxic T cell line, CTLL-2. The specific activity shall be not less than 3×107IU/mg.

Formulation:

Lyophilized from a 0.2μm filtered solution in 10mM Phosphate buffer containing 0.3% human serum albumin.

Reconstitution:

It is recommended to reconstitute the lyophilized rHuIL-2 in 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.
