Cynomolgus Monkey NK Cells
Purified Cynomolgus Monkey NK cells (Macaca fascicularis) for cytotoxicity assays, ADCC studies, and NK cell therapy development. Isolated by immunomagnetic selection with high purity.
The Cynomolgus Monkey
Macaca fascicularis
The cynomolgus macaque is the most widely used non-human primate in biomedical research, valued for its close physiological and immunological similarity to humans.
With over 60% genetic homology for key immune receptors, cynomolgus monkeys provide highly translatable data for drug development, making them ideal for immunology, infectious disease, and toxicology studies.
Human Similarity
~93% genetic homology with extensive immune receptor cross-reactivity
Global Availability
Multiple geographic origins with established breeding colonies
Regulatory Accepted
FDA & EMA preferred species for biologics safety assessment

Common Research Applications
Cynomolgus Monkey NK Cells are research-grade cynomolgus macaque primary cells intended for preclinical and translational research. Each order includes a Certificate of Analysis (COA) with lot-specific information including viability and purity data.
Natural killer (NK) cells are innate immune effectors critical for cancer immunotherapy research and viral immunity studies.
Common applications
- Cancer immunotherapy development
- NK cell-mediated cytotoxicity
- Viral immunity research
- Antibody-dependent cellular cytotoxicity (ADCC)
- Innate immune profiling

Geographic Origins Guide
Select the optimal origin for your research requirements
Chinese Origin ★ MOST COMMON
mainland
Chinese-origin cynomolgus are no longer exported by China. Cynomolgus macaques are not native to China and were historically imported from Cambodia, Vietnam, Laos, and Indonesia. Current samples are sourced from US breeding colonies established from China-line imports.
Mauritian Origin ★ DEFINED GENETICS
island
Mauritian cynomolgus have limited MHC diversity due to founder effects, making them valuable for immunology studies requiring genetic consistency.
Cambodian Origin ★ SOUTHEAST ASIAN
mainland
Cambodian-origin animals offer a Southeast Asian source with genetics that have not been mixed with other country lineages in the same way seen in some China-line populations.
Vietnamese Origin ★ SOUTHEAST ASIAN
mainland
Vietnamese cynomolgus provide another Southeast Asian option for programs that require distinct lineage sourcing or supply chain diversification.
Indonesian Origin ★ ISLAND ORIGIN
island
Indonesian-origin cynomolgus were among the earliest origins used in preclinical research and represented one of the largest research populations before China entered the market.
Philippine Origin ★ ISLAND ORIGIN
island
Philippine-origin cynomolgus were one of the first origins used broadly in research, with a long history as a trusted and widely used model.

Our scientific team can advise on the optimal origin for your study design and regulatory requirements.
Typical purity is >80% CD56+/CD16+ NK cells as assessed by flow cytometry. NK cells are enriched by immunomagnetic negative selection to preserve surface receptor integrity. Purity and viability data are included on the Certificate of Analysis.
Many anti-human NK markers cross-react with cynomolgus and rhesus monkey NK cells, including CD56, CD16, NKG2D, and NKp46. Cross-reactivity varies by antibody clone. We can provide validated clone recommendations for your species.
Thaw rapidly in a 37°C water bath until a small ice crystal remains. Transfer dropwise into pre-warmed NK cell medium with IL-2. Centrifuge at 300g for 10 minutes, resuspend in fresh medium. Allow overnight resting with low-dose IL-2 (100 U/mL) before cytotoxicity or ADCC assays.
Post-thaw viability is typically ≥70% for cryopreserved NK cells. NK cell function (cytotoxicity, ADCC) recovers optimally after overnight IL-2 stimulation. Fresh cells are shipped with ≥90% viability.
Yes. We support donor reservation and repeat-donor programs. Donor demographics and health records are available. NK cell donor variability in cytotoxicity is normal; we can pre-screen donors for high cytotoxic activity on request.
