Executive Industry Relevance

Solid phase microextraction (SPME) enables direct, minimally invasive sampling of metabolites from graft tissues, supporting objective assessment of organ quality prior to transplantation. This probe-based approach provides actionable metabolic and lipidomic data, informing early go/no-go decisions and reducing biological uncertainty in organ selection workflows. Integrating SPME-derived analytics enhances predictive confidence at a critical inflection point in the transplant pipeline.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct interrogation of tissue metabolic state for functional assessment.
• Supports biological de-risking by revealing early markers of organ viability or rejection.
• Provides quantitative data to inform target validation in organ preservation research.

Screening & Assay Development

• Facilitates preparation of validated tissue samples for downstream metabolomic and lipidomic assays.
• Improves assay reproducibility by standardizing metabolite extraction from intact tissues.
• Enables scalable, high-throughput screening of organ quality using consistent probe-based sampling.

Translational & Preclinical Research

• Aligns metabolic profiling with disease-relevant endpoints in transplantation models.
• Supports translational continuity by linking pre-harvest tissue state to post-transplant outcomes.
• De-risks advancement decisions by providing mechanistic insight into graft function.
