Product Overview
Description:
Dehydroergosterol is a naturally occurring, intrinsically fluorescent sterol analog that closely mimics the biophysical properties and membrane partitioning behavior of endogenous cholesterol. Featuring a distinct ultraviolet excitation and emission profile, this stable fluorescent probe is widely utilized for real-time membrane mapping, sterol environment imaging, and tracking intracellular lipid trafficking pathways.
