CD56 Enrichment: Advancing NK Cell Isolation & Immunotherapy
Clinical-Grade NK Cell Isolation for Cancer & Viral Immunity
Using CD56 (NCAM) as a surface marker to isolate highly cytotoxic Natural Killer cells โ powering tumor-targeting immunotherapy, HSCT support, and neurobiology research.
CD56 Enrichment is a process that isolates NK cells (Natural Killer cells) using CD56, also known as Neural Cell Adhesion Molecule (NCAM). This surface marker is highly expressed on NK cells and subsets of T cells, playing a vital role in immune defense, cell-to-cell interactions, and migration. CD56 Enrichment is essential in NK cell isolation, cancer immunotherapy, and immunology research.
CD56+ Cell Subtypes
CD56แตสณแดตแดณสฐแต NK Cells
Immature, cytokine-producing cells with immunoregulatory functions. Found primarily in lymph nodes.
CD56แตแดตแต NK Cells
Highly cytotoxic, efficient in targeting tumor or virally infected cells. The primary cytotoxic subset in peripheral blood.
CD3โป CD56โบ NK Cells
Standard phenotype for adoptive NK cell therapy โ no T cell receptor, pure NK cytotoxicity.
Applications of CD56 Enrichment in NK Cell Isolation
Cancer Immunotherapy
Enriched NK cells are used for tumor-targeting immunotherapy without prior sensitization.
Stem Cell Transplantation
CD56 Enrichment helps improve outcomes and reduce GVHD in HSCT.
Viral Immunity
NK cells enriched via CD56 play a key role against HIV, hepatitis, and influenza.
Neurobiology Research
CD56 is expressed in neural tissues, aiding stem cell and neuroscience studies.

Frequently Asked Questions
Is CD56 only found on NK cells?
No. While CD56 is a primary marker for NK cells, it is also expressed on a subset of T cells (NKT cells), some dendritic cells, neuroendocrine cells, and neural tissue. In hematological contexts, however, CD56 is predominantly used to identify and isolate NK cells from peripheral blood or bone marrow.
What are the benefits of CD56 Enrichment?
CD56 Enrichment provides highly purified NK cell populations with excellent viability. This enables more accurate cytotoxicity assays, consistent immunotherapy product manufacturing, reduced non-specific immune activity in transplant settings (lowering GVHD risk), and scalable research applications.
How does CD56 Enrichment support cancer immunotherapy?
CD56-enriched NK cells are used in adoptive cell transfer therapies where they are infused into patients to target and kill tumor cells without requiring prior sensitization. CD56dim NK cells are especially cytotoxic against hematologic cancers, and CD56bright cells contribute immunoregulatory cytokines that shape the anti-tumor immune environment.
Does Genestac provide custom NK cell isolation?
Yes. Genestac Therapeutics offers fully customized CD56 enrichment protocols, including subtype-specific isolation (CD56bright vs CD56dim), depletion of CD3+ T cells for purer NK products, and downstream activation or expansion services โ all under GMP-compliant conditions with full QC reporting.
