Here we demonstrate that the addition of glycerol to the buffer does not degrade the switching behaviour of the dyes Alexa Fluor 647 and Alexa Fluor 568 in dSTORM measurements, which shows that this approach is suitable for dSTORM. Additionally, we report evidence that sealed sample geometries as used in our experiments reduce photobleaching due to the lower influx of oxygen into the imaging buffer.Scientific reportsSwitching behaviour of dSTORM dyes in glycerol-containing buffer.PMC7426933SFB 944Huve JKlingauf JGoossen-Schmidt NCSchnieder MfalseSwitching behaviour of dSTORM dyes in glycerol-containing buffer.To suppress optical aberrations caused by refractive index mismatch, we employ glycerol-immersion objectives in conjunction with fused silica cover glasses and imaging buffers with a high glycerol content.
