Karmienie FITC-dekstranem: metoda ilościowego określania przepuszczalności jelit u C. elegans

Executive Industry Relevance

Quantifying intestinal permeability in C. elegans using FITC-dextran feeding provides a robust, scalable readout for barrier integrity in response to bacterial or chemical exposures. This assay enables early-stage mechanistic de-risking and supports predictive confidence in target validation for gut barrier function. The method is positioned for portfolio triage where intestinal permeability is a key translational endpoint.
