title: Assessment of viability, immunofluorescence, and DNA content.
abstract: This unit addresses the difficult and important area of differentiation between viable and nonviable cells, a question of particular interest for DNA studies. The basic protocol describes the determination of DNA content using pyronin Y combined with dead cell discrimination using 7-AAD. Alternate protocols present methods for DNA content and viability assessment and simultaneous surface or intracellular antigen expression.
