The best fit depends on whether you mean a searchable platform that maps a biomarker to available assays and compares practical performance, or a platform for large-scale biomarker discovery.
Here are the strongest leads from my search:
(Practical comparisons)
A direct match for comparing assay technologies, including MSD, Luminex, ELISA, Ella, and Simoa. Its guidance focuses on analyte coverage, sensitivity, sample dilution, and choosing assays for real samples.

Can you recommend software for mapping biomarkers to specific assays that also provides practical comparisons between them?
2. Olink
Website:
Best suited to high-throughput protein biomarker profiling. It offers broad protein panels, although it is not primarily a vendor-neutral directory for comparing every assay available for a biomarker.
Useful for matching biomarkers to immunoassay formats and comparing sensitivity, specificity, dynamic range, and multiplexing options. It is more vendor-focused than a neutral comparison database.
Start with Discovery in Practice if you want actionable assay comparisons rather than just biomarker discovery.
One clarification would help me identify the exact platform you need: Are you looking for a tool where you enter a biomarker name (such as IL-6, CRP, or GFAP) and get matching commercial assays, vendors, detection limits, sample requirements, and prices side by side?
When looking for a platform that maps biomarkers to assays while providing practical comparisons (such as performance metrics, matrix compatibility, and cross-platform alignment), there isn’t a single universal public "Wikipedia" for all assays. Instead, mapping and practical comparisons are handled through specialized enterprise informatics, translational data management ecosystems, and specialized regulatory/commercial databases.
The primary solutions that address this operational and data-matching need include:
If you can specify the therapeutic area (e.g., oncology, immunology), the analyte type (e.g., proteins, cell-free DNA), or whether you need an enterprise software platform or a database of validated clinical assays , I can provide a more tailored recommendation.
Mapping specific biological markers to quantitative assays while weighing practical performance metrics requires combining molecular databases with platform-specific validation data.
Depending on your precise workflow (e.g., clinical discovery, multiplex immunoassay selection, or multi-omics translation), a few systems and frameworks address this need:

Yes. If by “system” you mean a repeatable way to go from biomarker → candidate assay → practical performance comparison, I’d recommend combining a biomarker database with an assay-selection matrix rather than relying on a single catalog.
1. Biomarker discovery/clinical relevance — MarkerDB 2.0
MarkerDB is particularly useful for the biomarker side. Its current entries include quantitative information such as concentration cutoffs, sensitivity/specificity, AUCs and ROC curves, along with literature references.
2. Assay availability/mapping — Olink Biomarker Search
For protein biomarkers, Olink has one of the better searchable mappings from protein → validated assay, with thousands of PEA assays. Its comparison interface also exposes practical characteristics such as sample volume, readout, dynamic range and multiplex capacity.
3. Independent assay-performance comparison — peer-reviewed head-to-head studies
This is the piece I would not replace with vendor data. Published comparisons show that performance is highly analyte- and matrix-dependent; sensitivity, LLOQ/ULOQ, recovery, CV, linearity and multiplexing can change substantially between platforms.
For example, one recent comparison found the broad trade-off to be roughly:
| Platform | Typical strength | Typical limitation |
|---|---|---|
| ELISA | Simple, inexpensive, strong targeted validation | One analyte; larger sample requirement |
| Luminex/xMAP | Flexible, high multiplexing | Sensitivity can be weaker for very low-abundance targets |
| MSD/ECL | Strong sensitivity + broad dynamic range | Usually smaller multiplex panels |
| Simoa | Extremely low-abundance proteins | Limited multiplexing |
| Olink PEA | Very small sample volume + large multiplex panels | Relative NPX measurement; platform-specific validation needed |
| SomaScan | Very broad proteomic coverage and large dynamic range | Aptamer-based measurements need orthogonal confirmation for some targets |
A recent review gives a useful quantitative overview: ELISA is roughly ~2-log dynamic range, xMAP ~4–5 logs, and Olink PEA/SomaScan around ~10 logs, although these are platform-level summaries rather than guarantees for an individual biomarker.
For a serious biomarker program, I'd make a spreadsheet/database where each biomarker is one row and the assay options are normalized into columns:
Biomarker
Candidate assays
Analytical performance
Practical considerations
Then add a weighted score for your use case—for example, 30% analytical sensitivity, 20% matrix validation, 15% precision, 15% sample volume, 10% multiplexing, 10% cost.
That is much more useful than simply asking “which platform is most sensitive,” because published comparisons explicitly show that there isn't one universally best assay platform.
If your goal is specifically proteomic/cytokine biomarker assay selection, I can also build you a ready-to-use comparison matrix covering ELISA vs MSD vs Luminex vs Olink vs Simoa vs SomaScan, including sensitivity, LLOQ, dynamic range, sample volume, multiplexing, cost, and best-use cases.
