Cyto-Chex Stability Data

TokuTBNK Cytometry

Preservation data on our 15-Marker Spectral Panel

Cyto-Chex like fresh by spectral flow

CytoChex delivers fresh-level accuracy at 24 hours, keeping immune cell frequencies aligned with fresh EDTA.

0% Bias
Cyto-Chex at 24 hours matches fresh EDTA with no shift in immune cell frequencies.
± 0.7%
Immune cell frequencies agree within >1% of fresh EDTA, confirming that Cyto-Chex preserves true biology even with delayed processing.
100%
Leukocyte populations remain within ±3 percent after 24 hours of Cyto-Chex preservation

7 Day Stability

Teiko extends your collection window to 7 days at room temperature, keeping cell frequencies and counts steady.

±25%
Maximum change across all major immune populations over seven days.
<7%
When averaging all three donors, every immune population changed <7% from Day 1 to Day 7.
3%
B cell counts stay within about 3% of baseline on average across three donors.

Precision in Every Run

Absolute immune cell counts remain consistent across runs, supporting reliable sample analysis with TokuTBNK.

95%
Percent of immune cell populations achieving both intra- and inter-run precision thresholds in TokuTBNK testing.
5%
Median intra-run CV percent for absolute immune cell counts using the TokuTBNK panel.
11%
Median inter-run CV percent across three independent runs of the same CytoChex preserved whole blood sample.

TBNK profiling built for real-world clinical trials

From 7-day whole blood stability to reproducible gating and rapid turnaround, TokuTBNK ensures consistent, submission-ready immune profiling for global studies.

7-day whole blood sample stability with Cyto-Chex

Whole blood maintains reliable immune frequencies and absolute counts for seven days at room temperature.
