Data

Background

IL-2 is a 17.2 kD cytokine signaling protein that is the regulator of the proliferative and suppressive phases of the immune response, and stimulates growth and differentiation of B cells, NK cells, LAK cells, monocytes, and oligodendrocytes. It functions as a primary regulator of T cell homeostasis. Il-2 regulates the activities of white blood cells and plays a role in the immune system via “self” and “non-self” discrimination. IL-2 is a prime candidate in immunotherapeutics for both increasing T cell levels/function and for augmenting vaccine-elicited viral-specific T cell responses. IL-2 signal can be transduced via 3 different signaling pathways that include the JAK-STAT, PI3K/Akt/mTOR and MAPK/ERK pathways. Aldesleukin is a form of recombinant interleukin-2 for the treatment of cancers including malignant melanoma and renal cell cancer. Furthermore, there is additional therapeutic potential for IL-2 mAb use with transplants and autoimmune disease.

Protein Details

Purity
>97% by SDS-PAGE and analyzed by silver stain.
Endotoxin Level
<0.1 EU/µg as determined by the LAL method
Biological Activity
The biological activity of Human IL-2 was determined in a cell proliferation assay using an IL-2 dependent murine cytotoxic T cell line, CTLL-2 (Gearing, A.J.H. and C.B. Bird in Lymphokines and Interferons, a Practical Approach. 1987, M.J. Clemens, A.G. Morris and A.J.H. Gearing, eds., IRL Press, p. 295). The expected ED50 for this effect is typically 0.25 - 0.5 ng/ml.
