Description

Fluorescein octadecyl ester (ETH 7061) is a lipophilic fluorescent dye derived from fluorescein, modified with a hydrophobic chain, giving it the ability to partition into lipid environments while retaining the fluorescent and pH-sensitive characteristics of fluorescein. The long alkyl chain allows Fluorescein octadecyl ester to embed stably in lipid bilayers, membranes, or hydrophobic polymer matrices. Fluorescein octadecyl ester acts as a fluorescent pH or ion indicator embedded in polymers or membranes. It can be used in membrane labeling, liposome studies, and ion-selective electrode membranes (e.g., Ca²⁺, K⁺ detection), particularly in chemical sensing and biosensing applications. Optimal fluorescence can be seen at pH 7-8. Fluorescence Emission: ~520nm.
