Fluorescent DOTAP (Cat No.:I043909) is a fluorescently labeled lipid used primarily in cell membrane research and drug delivery systems. DOTAP is a cationic lipid commonly employed for creating liposomes, which can encapsulate therapeutic agents, such as RNA, DNA, or drugs, to facilitate cellular uptake. The fluorescent label allows researchers to track the liposomes in live cells using fluorescence microscopy or flow cytometry. Fluorescent DOTAP is especially useful for studying the efficiency of liposomal delivery, gene transfection, and cellular uptake mechanisms, aiding in the development of targeted delivery systems and gene therapies.
