We are thrilled to unveil our latest innovation for drug developers: a spectral flow cytometry panel using fixed whole blood collected with our TokuKit. This cutting-edge service allows you to analyze 146 immune populations with precision in our CLIA-registered lab.
This table showcases the precision of the assay, demonstrating high reproducibility with low median % CV values for both inter-run and intra-run measurements of phenotypic cell populations and functional marker subsets.

Why Choose Spectral Flow Cytometry?
Spectral flow cytometry takes immune monitoring to the next level:
- Rapid speeds: Receive publication-quality results on ~100 samples in as little as ~6 weeks.
- Read More, Analyze Deeper: Profile 146 immune cell populations and functional marker subsets with unparalleled resolution, covering T cells, B cells, NK cells, monocytes, dendritic cells, and their subsets, in each whole blood sample. You can theoretically measure up to 280 populations on this panel, allowing for detailed pharmacodynamic assessment.
- Better Data Quality: Spectral unmixing minimizes signal spillover, ensuring accurate detection of co-expressed markers.
- Easier data comparability: If you know conventional flow, you can interpret spectral flow data easily.
Why Choose TokuKit for Fixed Whole Blood?
- Access more clinical sites: No centrifugation or fresh blood processing required—collect, fix, and stabilize at the clinical site in under 20 minutes with our TokuKit.
- Unmatched Stability: Samples are stable for up to 24 months at -80°C in our accelerated stability studies, enabling true longitudinal studies and batch normalization.
- Overcomes the limitations of banked PBMCs: PBMC lose granulocytes, have higher variability in viability, cost $200-$300 per sample, and require specialized equipment and training.
- Proven Performance: Achieves a 0.97+ correlation between live and fixed whole blood population frequencies by spectral flow cytometry.
Our service is ideal for:
- Global, multi-site clinical trials that need standardized sample handling.
- Longitudinal immune monitoring for pharmacodynamic studies.
- Reducing variability and enhancing statistical confidence in your results.
We’re solving the three biggest problems in cytometry on clinical trials: getting a blood sample, measuring hundreds of populations, and making sense of it all.
