Active Recombinant Mouse Il2 Protein

• Cat.No.: Il2-105M
• Product Overview: Purified recombinant protein of Mouse interleukin 2 (Il2) (Ala21-Gln169) without tag was expressed in E.coli.

Specification

• Description: Produced by T-cells in response to antigenic or mitogenic stimulation, this protein is required for T-cell proliferation and other activities crucial to regulation of the immune response. Can stimulate B-cells, monocytes, lymphokine-activated killer cells, natural killer cells, and glioma cells.
• Source: E. coli
• Species: Mouse
• Bio-activity: The ED50 is 0.10-0.40 ng/ml, corresponding to a specific activity of 2.5 - 10 x 10^6 units/mg, determined by a dose dependent stimulation of HT-2 cells.
• Molecular Mass: 17.2 kDa
• Endotoxin: Less than 0.01 ng per µg protein as determined by the LAL method
• Purity: >98%, as determined by Coomassie stained SDS-PAGE.
• Stability: Unopened vial can be stored between 2 centigrade and 8 centigrade for up to 2 weeks, at -20 centigrade for up to 6 months, or at -70 centigrade or below until the expiration date. Aliquots can be stored between 2 centigrade and 8 centigrade for up to one week and stored at -20 centigrade or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
