Cells were then seeded on 22?mm22?mm #1.5 coverslips at a density of 4104 cells/cm2 and cultured for 24?h. Microtubule and actin filament staining: For microtubule imaging, cultured cells were then Tubacin extracted twice for 30?seconds with pre\heated MTSB (PEM Triton X, 80?mM PIPES pH?6.8, 5?mM EGTA, 1?mM MgCl2, 0.5?% Triton X\100). reaction conditions inherent to the process bring about strong fluorescent signal loss during polymerization and digestion and thus limit the brightness of the signal obtained post expansion. Here, we explore the impact of stabilizer\containing organic fluorophores in ExM, as a mitigation strategy for this radical\induced dye degradation. Through direct conjugation of 4\nitrophenylalanine (NPA) to our previously developed trifunctional reagents, we validate and demonstrate that these multifunctional linkers enable visualization of different organelles with improved fluorescent intensity, owning to protection…
