Stabil isotopmärkning av peptider genom reduktiv dimetylering (redi märkning) är en snabb, billig strategi för noggranna masspektrometri-baserad kvantitativa proteomik. Här visar vi en robust metod för beredning och analys av proteinblandningar med hjälp av redi strategi som kan tillämpas på nästan alla prov typ.
