Metabolic Assays for Detection of Neutral Fat Stores.

Lipid droplets (LDs) are ubiquitous intracellular structures whose formation, growth, and maintenance are highly regulated (Wang , 2013; Ranall , 2011; Goodman, 2009). Lipid metabolism and droplet dynamics are of considerable interest to agriculture, biofuel production, viral pathology, nutrition, and cancer biology (Walther and Farese, 2009; Liu , 2010). Accumulation of fatty acids and neutral lipids in nonadipose tissues is cytotoxic (Kourtidis , 2009).
