Species of Origin
His Tag (C-term)
Lyophilized from a 0.2 µm filtered solution of PBS, pH 7.4.
>98% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 16.2 kDa.
The protein migrates as 13 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to induce proliferation in CTLL2 cells. The ED₅₀ for this effect is <0.5 ng/mL.
<0.1 EU per 1 μg of the protein by the LAL method.
Interleukin-2 (IL-2) is a four bundle, immuno-modulatory cytokine which is expressed predominately by antigen-simulated CD4+ T cells, CD8+ T cells, natural killer (NK) cells, and dendritic cells (DC). IL-2 plays a fundamental role in promoting NK cell proliferation, cytotoxicity, and B cells differentiation. IL-2 modulate T cell differentiation programs, promoting naïve CD4+ T cell differentiation into T helper-1 (Th1) and T helper-2 (Th2) cells.
