Chol-N3 is a bioorthogonal-based chol probe. Chol-N3 can combine with super-resolution fluorescence microscopy (SRM), providing direct visualization of nanoscale lipid heterogeneity in the cell surface of resting living cells[1]. Chol-N3 is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups. | [References]
