简介：
Overview
Nile red staining of fixed Caenorhabditis elegans is a method for quantitative measurement of neutral lipid deposits, while oil red O staining facilitates qualitative assessment of lipid distribution among tissues. These techniques are essential for understanding lipid metabolism and its regulation.
