TESTED APPLICATIONS:
BIOLOGICAL ACTIVITY: The ED50 was determined by the dose dependent stimulation of murine CTLL - 2 cells is < 0.2 ng/mL, corresponding to a specific activity of > 5 x 106 units/mg.
psi-iconProperties
PURITY:Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin level is less than 0.1 ng per μg (1EU/μg).
PHYSICAL STATE:Lyophilized
STORAGE CONDITIONS:The lyophilized IL-2 recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted IL-2 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing IL-2 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

psi-iconBackground and References
BACKGROUND:IL-2 is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. IL-2/IL-2R signaling is required for T-cell proliferation and other fundamental functions which are essential for the immune response. IL-2 stimulates growth and differentiation of B-cells, NK cells, lymphokine activated killer cells, monocytes, macrophages and oligodendrocytes. Recombinant murine IL-2 is a 17.2 kDa protein, containing 149 amino acid residues.
