• Endotoxin-free*
• Animal-derived product free
• High Activity
• Authentic Glycosylation

Xeno-free IL-2 is expressed in human 293 cells as a monomeric glycoprotein with an apparent molecular mass of 15 kDa. This cytokine is produced in a human cell expression system with serum-free, chemically defined media. Production in human 293 cells offers authentic glycosylation, which contributes to stability in cell
growth media.
