Key Applications
- Antibody validation and optimization
- Biomarker discovery and target expression mapping
- Indication stratification and tissue profiling
- Preclinical immuno-oncology screening and hypothesis testing

Analytical Assays For Endpoint Data Collection
Our Patient Derived Xenograft (PDX) Tissue Microarrays (TMAs) deliver more than static samples. They provide a functional starting point for integrated oncology research. By offering hundreds of PDX tumor cores per slide, our TMAs eliminate bottlenecks in early-phase validation and help scientists quickly identify which targets matter.
Overview
Patient-Derived and Clinically Annotated
Assembled from our TumorGraft™ models, our TMA cores reflect Western clinical treatment history and come annotated with genomic and histopathologic data.
High-Content, Low-Variability Format
Each slide contains cores from a diverse patient cohort, reducing staining variability and enabling reliable IHC/IF analysis at scale.
Ready for IHC and Multiplexing
Built on FFPE format, our TMAs are compatible with standard histology workflows and multiplex biomarker readouts.
Pipeline-Linked, Not Standalone
TMAs are directly traceable to Champions' matched preclinical models, including PDX, and TumorGraft3D™ organoidsex vivo models, enabling immediate, functional follow-up.


What Comes Next
Each array isn't just a diagnostic snapshot, it's a launchpad. When a marker or expression pattern is identified, we enable seamless progression into:
Using a prostate cancer-specific TMA, a client validated AR expression patterns across resistant patient samples, then used matched ex vivo models to test a dual inhibitor strategy. The result: clear translational direction in weeks, not months.
