The NTK offers a portfolio of exploratory prototype assays designed to generate high quality, reproducible, and comparable biomarker data across academic and industry cohorts.The NTK assays can be run on the fully automated Elecsys® platform in four NTK qualified labs. This ensures that high quality, reproducible data can be compared to multiple datasets -- maximizing how results can be interpreted.
How to become a partner
- Request and sign an NTK collaboration agreement and pay an access fee
- Submit a measurement request and provide basic cohort details (number of samples and markers to be measured). The request should be placed as early as possible to ensure lab availability.
- Based on the request, a measurement time slot will be reserved at one of the NTK testing sites. A small amendment to the collaboration agreement (description of the measurement, number of samples, markers to be measured, timeline) will need to be signed. A material transfer agreement with the designated NTK testing site will also be needed.
- A per determination fee (one sample measured with one biomarker) is charged per cohort. This covers all costs, including reagents and lab fees.

The NeuroToolKit (NTK) is the result of an academic and industry partners to generate high quality, reproducible, and comparable biomarker data. Research collaboration will be instrumental in generating evidence to clarify the use of biomarkers in clinical trials and routine clinical practice. This should accelerate the development of In Vitro Diagnostics (IVD) biomarkers that: (1) support clinical screening, diagnosis, and prognosis, (2) track pharmacodynamic responses, and (3) monitor drug efficacy. Roche Diagnostics uses the collaborative NTK approach to accelerate and inform decision-making regarding the clinical utility and IVD development of medical value assays.
The NTK offers a portfolio of exploratory prototype assays designed to generate high-quality comparable clinical biomarker data across academic and industry cohorts. The NTK assays can be run on the fully automated Elecsys® platform in four NTK qualified labs. This ensures that high quality, reproducible data can be compared to multiple datasets - maximizing how results can be interpreted. By clarifying the clinical utility of biomarkers and how they can be used in clinical trials, it identifies and supports those biomarkers which need to be developed further.
The NTK portfolio for CSF currently includes robust prototype assays to measure any combination of the following biomarkers: Aβ42 (IVD ), Aβ40, t-tau (IVD ), p-tau181 (IVD ), neurogranin, GFAP, IL-6, YKL-40, sTREM2, NfL, S100B and α-synuclein.
The NTK portfolio for plasma currently includes robust prototype assays to measure any combination of the the following biomarkers:s Aβ42 high sensitive, Aβ40, tTau, NfL, sTREM2, YKL-40, IL-6 (IVD), S100B (IVD in serum), GFAP, GDF-15 (IVD in plasma in development), IGFBP7, NSE IVD in serum) pTau181 (IVD in plasma in development), APOE4 (IVD in plasma in development) .
Additional biomarkers that will soon be available: TDP 43 (serum), SNAP 25 (CSF/plasma), NPTX 2 (CSF/plasma).
The required volume depends on the selected biomarker to be measured and sample type. Please see below for more details.
The exploratory prototype assays are for human research only (for basic research or for early investigation of potential clinical utility of biomarkers). Measurements made with the NTK robust prototype assays must not be used for any medical and/or clinical decision making.
We have a strong foundation of reliable, comparable and high quality biomarker data, which highlights the benefits of using the Elecsys® technology in neurological diagnostics.
Although amyloid plaque deposition and tau tangles are the main pathological hallmarks of the disease, neuroinflammation, microglial overactivation and axonal/synaptic neurodegeneration to play an important role in AD pathogenesis. These pathological processes are complementary to the amyloid cascade hypothesis and are reflected by changes in biomarker levels measured in the NTK panel.
Similar to AD, neurodegenerative diseases such as Parkinson’s disease and Multiple Sclerosis involve a series of pathological processes that include synaptic and axonal degeneration, inflammation and microglial overactivation. Assessing specific markers of each disease's pathological process may help explore potential biomarker disease profiles to reach a differential diagnosis.
The NTKApp is a cloud based data analytics tool to curate, analyze and compare biomarker datasets and results - maximizing the interpretability of the generated results. It is deployed on the AD Workbench, a trusted cloud based platform for collaborative data science.
The NTKApp consists of three interlinked apps. This allows users to upload and curate, analyze, and compare biomarker datasets and results from all over the world in a few simple clicks. Thanks to the NTKApp built-in virtual machine, users have the option to import, shape, and run their own statistical analysis pipeline, which can later be shared within the NTK community.
The NTKCuration App module offers user-friendly data upload. Biomarker data needs quality control and standardization before being used in the NTKAnalysis App. - The NTKCuration App saves time and money because this automated data standardization process minimizes human error and allows comparability across datasets.
The NTKAnalysis App allows users to select from a suite of powerful descriptive statistics to gain immediate insight into their data. Outputs from these analyses are available in publication-quality tables and interpretable graphical visualizations, which can be saved locally.
The NTKMeta-Analysis App allows biomarker data to be compared with other data across the community. The cloud can be harnessed to select, stratify, and compare biomarkers and clinical characteristics in a global way. The NTKMeta-Analysis App also sheds light on shared data, resources, and objectives, providing support for existing and new clinical use cases based on collective evidence. This enables results to be contextualized and new hypotheses and evidence to be generated.
The NTKApp is a new neurological tool to exchange new ideas, encourage valuable research, and support industry partnerships – all to accelerate biomarker discovery and development.
