The control that doesn't exist yet
Some panels need a biomarker no one stocks. Some assays need a phenotype only a handful of labs care about. The alternatives are donor cells that vary week to week, cell lines that drift, or beads that don't behave like cells. Or you tell us what you need, and we engineer a cell mimic to match. That's what TruCytes® are.
A synthetic cell, built to your spec
Every TruCyte is built on the same polymer platform as our catalog products — scatter tuned to real cells, fluorescence that doesn't drift, surface biology at controlled densities. Custom just means you define the phenotype instead of picking from a list.
Your markers, your densities
Specify the surface antigens, the intracellular targets, the combinations. MESF-calibrated loading, so the MFI you design for is the MFI you get. Every lot.

The cases donor cells can't handle
Catalog controls cover the common panels. Custom is for the rest.
Rare phenotypes and low-frequency markers
Subpopulations that are hard to isolate. Markers at densities most donors don't express. Internal negatives that match the positives on everything except the thing you're measuring.

Ten weeks from brief to CoA
Custom doesn't mean slow. A typical engagement runs about ten weeks from the first scoping call to a released production lot.
1. Scoping call
Walk through the assay, the panel, the phenotype. We figure out what's feasible and what the design tradeoffs are before anyone writes a statement of work.

Custom doesn't mean experimental
Your custom lot is built, QC'd, and released against the same specifications as every other TruCyte we make.
<5% CV lot-to-lot
The MFI you hit in validation is the MFI you keep hitting. Measured across production, not modeled from a couple of runs.

Tell us what you need to control
The hardest part is writing the first brief. Our scientists will do it with you — phenotype, panel, assay, scale. No commitment, no pricing gate.
