Lipid staining is used to visualize neutral lipid droplets, membranous lipids, cholesterol, myelin lipids, and lipid-deposition-related structures in tissue, cell, or microbial samples. Different staining methods vary greatly in target recognition, sample pretreatment, and microscopic readout.

In biological experiments, “red-series reagents” can refer to chromogenic or staining reagents that appear red in visible light, as well as fluorescent probes and labels whose emission falls in red or far-red channels. Because “red” may denote apparent color, precipitated chromogenic ...
