Validation Data Gallery

  • Purity of recombinant human IL-2 was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

  • recombinant human IL-2 (HZ-1015) stimulates dose-dependent proliferation of the CTLL-2 (mouse cytotoxic T) cell line. Viable cell number was quantitatively assessed by Prestoblue Cell Viability Reagent. CTLL-2 cells were starved for 5 hours before treatment with increasing concentrations of GMP recombinant human IL-2 for 48 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 values range from 0.05-0.35 ng/mL.

Stability and Reconstitution

Stability and Storage Lyophilized proteins are stable for 1 year from the date of receipt if stored between (-20°C) and (-80°C). Upon reconstitution we recommend that the solution can be stored at (4°C) for short term or at (-20°C) to (-80°C) for long term. Repeated freeze thaw cycles should be avoided with reconstituted products.
Reconstitution Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein to 0.2 mg/mL in sterile 1x PBS pH 7.4 containing 0.1% endotoxin-free recombinant human serum albumin (HSA). Gently swirl or tap vial to mix.

Background

Interleukin-2 (IL-2) is a four-helix bundle, type I cytokine that functions as a growth factor for a wide range of leukocytes. In the immune system, IL-2 is essential for immune homeostasis, normal T regulatory cell function, and self-tolerance. It regulates immune cell homeostasis and has been used to treat a range of disorders including cancer and autoimmune disease. IL-2 signals through heterodimerization of the IL-2Rβ and IL-2Rγ receptor subunits (PMID: 25992858, 24907378, 15034008, 17981641).
