Healthy CD56+ NK Cells
About:Healthy CD56+ NK Cells are isolated from peripheral blood of healthy, consented donors. Ideal for immunology, cancer research, and drug discovery focused on natural killer (NK) cell function, cytotoxicity assays, and immune modulation. Disease-state CD56+ NK cells are available.
About Healthy CD56+ NK Cells
High-Purity Healthy CD56+ NK Cells for Immunology and Oncology Research
Healthy CD56+ NK Cells are isolated and cryopreserved from peripheral blood of rigorously screened, IRB-consented healthy donors. These natural killer (NK) cells are CD56-positive, CD3-negative lymphocytes essential to the innate immune response. Ideal for studies involving immune surveillance, cancer immunotherapy, cytotoxicity, and viral response mechanisms. Disease-state CD56+ NK cells are available.

Where can I find your complete catalog?
You can find our full product catalog here.
How long can samples be stored?
Storage depends on sample type but often cryopreserved samples stored in liquid nitrogen can be stored for years.
What customization options are available?
Extensive customization is available. To discuss your project request a quote or email us at learnmore@sanguinebio.com.
Do you offer prospective collections?
Sanguine offers flexible prospective collection services tailored to fit your research. For more information and to request a quote, please see: our prospective biospecimen collection services page.
What is the turnaround time for custom collections?
Timelines depend on condition, sample type, and I/E criteria but we often start collection within 2 weeks of signed agreement.
Do you have samples in stock?
YES - we have in-stock inventory. You can also email us at learnmore@sanguinebio.com as we continually get new samples in our inventory.
What does unique donor mean?
Each sample from a different individual - Unique donor means each sample comes from a different person, ensuring biological diversity in your study.
Are samples collected under IRB-approved protocols?
YES - "IRB-approved collection protocols" and IRB approval documentation available upon request. Sanguine utilizes two internationally-recognized IRBs (Advarra and WCG IRB) for review and approval.
