The lab’s investigators, using Interleukin (IL-2) as a “T-cell and NK-cell growth factor”, where experiencing inconsistent cell biological activity. After extensive analysis, the lab determined that the presence of animal origin materials was impacting the factors.
The lab required animal origin free (AOF) cytokines.
GeminiBio collaborated with the lab to identify and provide an IL-2 that was free of animal components and produced from E. coli in a recombinant process. This provided improved lot-to-lot biological activity and performance, supporting more predictable workflow performance in the proliferation of their natural killer (NK) cells.
