Colonoscopic Guided Pinch Biopsy in a Mouse Model: A Technique to Visualize and Extract Tissue Samples from Mouse Colon

Executive Industry Relevance

Colonoscope-guided pinch biopsy in mouse models enables direct visualization and precise extraction of colon tissue, supporting high-fidelity analysis of inflammatory and pathological changes. This technique strengthens early discovery and target validation by providing reproducible, minimally invasive access to disease-relevant tissue. Its integration enhances predictive confidence and translational continuity in gastrointestinal research pipelines.

Strategic Applications in Biopharma R&D
