By optimizing cell sorting technology and innovating culture systems, the company has achieved efficient expansion and precise purification of NK cells, with a cell purity of over 98%—far exceeding the industry average. Meanwhile, through genetic modification and functional enhancement technologies, the specificity of NK cells in recognizing tumor cells and their killing efficiency have been significantly improved. The in vitro tumor cell killing rate reaches over 92.6%, and the cells possess the inherent advantages of "not damaging normal tissue cells and causing no severe immune rejection," resulting in superior safety and tolerability.
