NK Cells
Natural killer cells with a validated cytotoxic profile — purity confirmed and functional activity verified for each lot.
COA per lotInnate immunity, characterized.
Natural killer (NK) cells are lymphocytes of the innate immune system, identified as CD56+ CD3−. 1CELL's NK cell populations have a validated cytotoxic profile and are delivered in an infusion-ready formulation.
Purity and functional cytotoxic activity are confirmed for each lot, with an optional HLA/KIR panel for matched applications.

Preserved as the product requires.
NK cells can require cryopreserved storage and cryogenic transport, or controlled cold-chain conditions, depending on formulation. 1CELL confirms the conditions with the source laboratory for each lot and coordinates packaging, transport and clinic handoff.
What the research says.
NK cells recognize and eliminate stressed or abnormal cells without prior sensitization. They are studied in oncology and immune research, including adoptive transfer approaches; many studies are early-stage.
NK cell therapies are investigational in most settings and should be used only under specialist supervision, within applicable regulation.
