Have Hillgene's K562 feeder cells been inactivated?

Yes. Hillgene's K562 feeder cells have been rigorously inactivated using 100 Gy irradiation.

After inactivation, the cells lose their proliferative capacity but retain their function as feeder cells, continuously providing cytokines and membrane-bound signals to support efficient expansion of NK and T cells.
