Product Description:
Human Cell Expressed | ||
Animal-derived product free | ||
Endotoxin-free* | ||
Very High Activity |
HumanKine® IL-1 beta expressed in human 293 cells has a very high activity with a typical ED50 of 0.02 to 0.08 ng/mL using a bioassay to measure stimulation of the proliferation of mouse D10S cells. In comparison with the E. coli expressed protein, IL-1 beta® is 50% more potent promoting human CD4+ T cell differentiation into Th17 cells. This cytokine is produced in a serum-free, chemically defined media.
