The ED50 is <0.1 ng/mL as measured by CTLL-2 cells, corresponding to a specific activity of >1 × 107 units/mg. Appearance
Lyophilized powder. Formulation
Lyophilized after extensive dialysis against 50mM Phosphate buffer, pH7.5, 5% Mannitol buffer. Endotoxin Level
<1 EU/μg, determined by LAL method. Reconstitution
Reconstitute the lyophilized recombinant Human Interleukin-2 (rHuIL-2) to 100 µg/mL using ddH2O. Storage & Stability
Lyophilized recombinant Human Interleukin-2 (rHuIL-2) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping
Room temperature in continental US; may vary elsewhere. Background
Recombinant human interleukin-2 (IL-2) expressed as Escherichia coli is isolated as insoluble aggregates of protein (inclusion bodies) after cell breakage. Interleukin 2 (IL-2), a cytokine secreted by activated T cells, promotes the differentiation and proliferation of lymphoid cells as well as enhances the cell-mediated immune response to infections. Therefore IL-2 has been used as an adjunctive immunotherapeutic agent to control some infectious diseases, such as leishmaniasis, leprosy, and HIV infection[1]. |
