Test-specific reagents
Specialized reagents for the SDF-Index research method.
General consumables, flow cytometers, and laboratory staffing remain separate.For research laboratories
Build the capacity to run DFI analysis in your laboratory.
FRAGSIGN, powered by SDF-Index, connects test-specific reagents, practical training, analytical software, and technical support for qualified research teams.
Research capability
Bring the workflow into your own laboratory.
Coordinate specimen preparation, flow-cytometry acquisition, and software analysis with your team’s research procedures.
- Train the personnel who perform and review the work.
- Connect wet-lab preparation to FCS acquisition and analysis.
- Define quality checkpoints and documentation responsibilities.
- Keep research methods and analytical decisions under laboratory oversight.
