A clearer workflow for DNA fragmentation research.
Bring acquired flow-cytometry data into one workspace for DNA fragmentation index (DFI) and high DNA stainability (HDS) analysis, quality review, and reporting.
powered by SDF-Index™
DFI + HDSQuality reviewResearch reports
From acquired data to reviewed output
Three steps. One research workflow.
FRAGSIGN brings the SDF-Index analytical workflow to qualified research laboratories.
- 01
Bring acquired data
Upload supported FCS files from your configured flow-cytometry research workflow.
- 02
Review and analyze
Review the run and quality information. Apply the configured SDF-Index analysis to generate DFI and HDS outputs.
- 03
Keep results in context
Review analytical outputs alongside run information and prepare a standardized research report.
Specimen handling, staining, instrument setup, and acquisition take place in your laboratory. Instrument, file, and workflow compatibility must be confirmed before use.
A defined research scope
Built for research questions.
Use analytical outputs within your research protocol. FRAGSIGN™ powered by SDF-Index™ is not intended for diagnosis or treatment decisions.
Each laboratory remains responsible for its methods, instrument configuration, quality processes, and review of research results.
- DFI
- DNA fragmentation index output from the configured analysis.
- HDS
- High DNA stainability output from the configured analysis.
