Cet article décrit une méthode d'isolement des noyaux à partir de tissus cérébraux humains frais congelés en utilisant des techniques mécaniques et de centrifugation. Le processus implique l'utilisation de tampons de lyse et de saccharose pour créer un gradient de densité pour une séparation efficace.
Isolating specific cell populations from complex tissues like the human brain is critical for de-risking target validation in neuroscience drug discovery. Fluorescence-activated nuclei sorting (FANS) enables high-purity isolation of nuclei from fresh-frozen tissue, supporting mechanistic studies of nuclear proteins and cellular heterogeneity. This approach improves predictive confidence in early discovery by providing reproducible, quantitative inputs for downstream assays and target engagement studies.
FANS integrates into the discovery continuum from target hypothesis testing through lead identification and preclinical validation by delivering purified nuclear fractions for functional and biochemical analysis.
