> 95% as determined by BisTris PAGE > 95% as determined by HPLC |
|
| Endotoxin Level | Less than 0.01EU per μg by the LAL method. | |
| Biological Activity | Measured in a cell proliferation assay using CTLL‑2 mouse cytotoxic T cells. The ED50 for this effect is 0.52 ng/mL. Test result was comparable to standard batch. | |
| Expression System | E.coli | |
| Theoretical Molecular Weight | 15.5 kDa | |
| Apparent Molecular Weight | The protein has a predicted 15.5 kDa same as Bis-Tris PAGE result. | |
| Formulation | Lyophilized from 0.22μm filtered solution in 100mM Acetic Acid. | |
| Reconstitution | Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in 100mM Acetic Acid. | |
| Storage & Stability | Upon receiving, the product remains stable up to 6 months at -20 °C or below. Upon reconstitution, the product should be stable for 3 months at -80 °C. Avoid repeated freeze-thaw cycles. |
| Target Background | Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15,5 - 16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 has essential roles in key functions of the immune system, tolerance and immunity, primarily via its direct effects on T cells. |
| Synonyms | IL2; T-cell growth factor; TCGF; Aldesleukin |
