Polar lipid dyes preferentially bind to polar lipids, which are a class of lipids with both hydrophilic and hydrophobic regions. These fluorescent dyes are useful for visualizing and studying lipid-rich cellular compartments, like the endoplasmic reticulum and mitochondria, in live and fixed cells.
Our LipoFluor-P1™ Polar Lipid Tracing Reagent is a cell-permeant fluorescent dye specifically designed for tracing lipids, including cholesterol, sphingolipids, and phospholipids showing their intracellular localization. Our LipoFluor-ER1™ is a cell-permeant stain specific for the endoplasmic reticulum. LipoFluor-ER1™ passively diffuses across the plasma membrane into the cell, stains at low concentrations and has minimal cytotoxic effects. It can be used as a real-time imaging reagent which can be imaged within minutes of addition and has minimal photobleaching.
