Description:

Recombinant human IL-2 produced in Yeast is a single, non-glycosylated, polypeptide chain containing 131 amino acids, one pair of disulfide bond and with 123 cys. aa. mutated to Ala aa, having a molecular mass of approximately 15.2kD.

Source: Yeast.

Molecular Mass: Approximately 15.2kD.

Purity: ≥98%, as determined by SDS-PAGE and HPLC method.

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. 

Formulation:

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

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 24 months from date of manufacture at -20°C to -70°C (tentative). It will be continuously updated based on stability data.

• Avoid repeated freeze-thaw cycles.
