WHAT WE OFFER
Two ways to get what your program needs.
Access research-ready inventory today, or commission a collection to your protocol. Specimens are supplied with de-identified clinical and demographic data, with requirements confirmed for your study.
BANKED SPECIMENS
Research-ready inventory, available now
Explore matched tumor and blood, treatment-naive cohorts, and specimens with documented treatment histories across cancer types and stages, alongside plasma, serum, tissue, and specialty matrices. Our team confirms the specimens and associated clinical data available for your study.
CUSTOM COLLECTIONS
Collected to your protocol
When your study needs something specific, we design the collection around it: indication, cohort criteria, specimen matrix, timepoints, and clinical data. Collections follow IRB/IEC oversight, informed consent, and documented chain of custody across our physician-guided network.
SPECIMEN MATRICES
The right format for your assay.
Collected and processed to preserve the analyte you care about, with pre-analytical handling defined up front and confirmed against your protocol.
| MATRIX | FORMATS AND HANDLING | APPLICATIONS |
|---|---|---|
| Whole blood and plasma | EDTA, heparin, Streck, or PAXgene; double-spin plasma as specified | ctDNA, cfRNA, methylation, fragmentomics, and proteomics |
| Serum | Clotted, centrifuged, and aliquoted | Protein biomarkers, metabolomics, and serology |
| Tumor tissue | FFPE blocks and slides, fresh-frozen tissue, and touch preps | NGS, IHC, TMA, spatial profiling, and orthogonal confirmation |
| Matched sets | Tumor and blood from the same donor; treatment-naive cohorts on request | Concordance, companion diagnostics, and MCED/MRD development |
| Buffy coat | Isolated from whole blood, on request | Germline reference |
| Other matrices | Urine, saliva, CSF, pleural fluid, BAL, and stool | Renal, neurological, respiratory, and GI diagnostics |
Availability, volumes, and handling details are confirmed against your protocol.

WHY DCN DX
Quality from collection to delivery.
Know how your specimens were collected, handled, and documented before they reach your lab.
Matched and longitudinal
Plan matched and longitudinal collections around treatment status, follow-up timepoints, and the clinical data your study needs.
Representative cohorts
An expanding Latin American collection network gives developers access to more diverse patient populations for studies aligned to intended use.
Quality and oversight
DCN Dx maintains ISO 13485- and ISO 9001-certified quality systems. Collections follow IRB/IEC oversight, informed consent, de-identification, and documented chain of custody.
Pre-analytical control
Standardized procedures and timestamps document collection, processing, and storage, helping you assess pre-analytical variables.
Research-ready network
Our team works with a physician-guided collection network to confirm feasibility, cohort criteria, and delivery timing for your study.
Diagnostic development expertise
Biospecimen specialists work alongside DCN Dx’s assay development and clinical research teams to align collections with the evidence your program needs.
