|
C-term |
|
Purity |
> 95% as determined by BisTris PAGE > 95% as determined by HPLC |
Endotoxin Level |
Less than 1EU per ug 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 15 ng/mL. Test result was comparable to standard batch. |
Expression System |
HEK293 |
Theoretical Molecular Weight |
20.1 kDa |
Apparent Molecular Weight |
Due to glycosylation, the protein migrates to 27-30 kDa based on Bis-Tris PAGE result. |
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
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. |
