Elettroforesi su gel di poliacrilammide nativo blu: una tecnica di separazione non denaturante per l'analisi di complessi di catene respiratorie mitocondriali intatti

Executive Industry Relevance

Blue native PAGE enables preservation of mitochondrial respiratory chain complexes in their native, functional state for size-based separation. This supports target validation in mitochondrial dysfunction pathways by maintaining complex integrity during analysis. The technique provides predictive confidence in early discovery by resolving intact complexes for mechanistic de-risking.
