Biospecimens you can trust for consistent results
We offer high-quality isolated immune cells from healthy, consented donors. Each cell type is carefully processed and cryopreserved to maintain viability and function for use in immuno-oncology, infectious disease, and cell-based assays.
Consistent, high-viability immune cells for advanced research
High-quality isolation
Cryopreserved for performance
Flexible customisation
Explore research applications
Immune responses
Investigate immune reactions to pathogens, vaccines, and therapies

Autoimmune disorders
Study the mechanisms underlying autoimmune and immunodeficiency conditions

Drug discovery
Develop immunotherapies and cancer treatments, including CAR-T cell therapies

We know every research project is unique
We offer fully customisable options for isolated immune cells to ensure you get exactly what you need
Donor profiles
Select donors based on HLA type, CMV status, age, sex, and other key criteria to match your study requirements.
Cell counts
Order large, consistent batches from a single donor to maintain reproducibility across experiments.
Cell types
Choose from a range of immune cell subsets, including CD4+ T helper cells, CD8+ cytotoxic T cells, NK cells, and more.
If our standard collection criteria do not meet your exact requirements, we can create bespoke collections designed for your study.

What are isolated immune cells?
Isolated immune cells are essential for understanding the immune system’s role in health and disease.
- CD19+ B Cells: Crucial for antibody production and humoral immunity
- CD14+ Monocytes: Key players in innate immunity and antigen presentation
- CD56+ Natural Killer (NK) Cells: Involved in the direct destruction of virally infected and tumour cells
- CD3+ Pan T Cells: Encompassing all T cell subsets, vital for adaptive immunity
- CD4+ T Helper Cells: Assist other immune cells in orchestrating immune responses
- CD8+ Cytotoxic T Cells: Responsible for targeting and eliminating infected or malignant cells
