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 is part of the body's natural response to microbial infection, and in discriminating between foreign ("non-self") and "self". IL-2 mediates its effects by binding to IL-2 receptors, which are expressed by lymphocytes.

Measure by its ability to induce CTLL-2 cells proliferation. The ED50 for this effect is <0.3 ng/mL. The specific activity of recombinant mouse IL-2 is approximately >3 106 IU/mg.
Endotoxin level:<0.1 EU per 1 ug of the protein by the LAL method.
Calculated Molecular Weight:18.2 kDa
Formulation:The protein was lyophilized from a solution containing 1X PBS, pH 7.4.
It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 ug/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Stability and Storage:
Lyophilized protein should be stored at -20 degrees Celsius for 1 year. Upon reconstitution, store at 2 degrees Celsius to 8 degrees Celsius for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20 degrees Celsius or -80 degrees Celsius for 3-6 months.
SDS-PAGE Image Name:mouse IL-2
