Natural killer (NK) cells play a major role in immune surveillance and in the early immune response to cancer and infections1,2. Beneficial anti-tumor responses have been observed, illustrating the safety profile and clinical potential of this treatment3,4. With an increasing availability of anti-cancer drugs, the role of NK cell-based approaches in novel combination therapies has rapidly escalated5,6.

The use of specific CliniMACS® Product Lines allows GMP-compliant manufacturing of NK cell products according to the needs given by a specific treatment concept.

Highly enriched NK cell products are generated by CD3 depletion followed by CD56 enrichment. A combined NK cell and natural killer T (NKT) cell product is produced by a single CD56 enrichment step. Heterogeneous NK cell products can be manufactured by either CD3 or TCRα/β depletion, optionally in combination with CD19 depletion. The latter two manufacturing strategies for NK cells allow co-enrichment of NK cells and accessory cells, such as monocytes and dendritic cells. In case of TCRα/β depletion, γ/δ T cells are also preserved within the NK cell product.

With our CliniMACS Prodigy® Instrument and MACS® GMP reagents that have been designed for clinical applications, you are ready to manufacture adoptive cell therapy products.
