Abstract
A new class of optical indicators which are capable of memorizing and preserving the spatial localization of intracellular analytes in a time resolved manner is described. The compounds comprise a chromophore carrying a photolabile group capable of undergoing an irreversible and detectable chemical transformation upon irradiation by light. The chromophore is linked to a binding site capable of binding an analyte, wherein binding of the analyte to the binding site alters an optical property of the chromophore, thus altering the ability of the photolabile group to undergo the chemical transformation. Methods and kits for memorizing the spatial localization of the analytes are also described.
