Monitoring Microalgal Neutral Lipid Accumulation with Nile Red
WebbThe widely applied Nile red (NR) method allows near real-time monitoring of microalgal neutral lipid accumulation. When added to a culture sample, optimally, the fluorescent dye NR penetrates the microalgal cell wall staining the intracellular neutral lipids, and the measured fluorescence is linearly correlated to the neutral lipid concentration.
