PPT-Determining Cell Viability

Cell Viability In biological systems viability often refers to an ability to maintain homeostasis Plasma membrane integrity DNA synthesis DNA content enzyme activity presence of ATP and cellular reducing conditions are known indicators of cell viability and cell death. Commonly used sperm viability assays em ploy mixtures of two or three dyes including fluorescein di acetate derivatives rhodamine 123 and reduced nucleic acid stains which target a variety of cellular components 14 Acridine orange which fluoresces a Conventional directcount assays of bacterial viability are based on metabolic characteristics or membrane integrity However methods relying on metabolic characteristics often only work for a limited subset of bacterial groups and methods for assessi GOVERNANCE OF COMPLEX SYSTEMS.
