SpheroRuler of Idylle is a monodispersed suspension of 1µm diameter spheres coated with 647-fluorophores giving a stable blinking in SMLM microscopy. Their consistent size and geometry make them very practical and reliable standards to assess the accuracy of your x-y or z measurements, 3D reconstruction methods or your image quality. Monodispersed and immobile in solution, they can also be used as rulers, for drift correction or as guides to help localize features on your biological samples.
It is great for dSTORM calibration experiments because you can use it on your preferred support and buffer. And SpheroRuler is also a simple shape easy to study when you are a dSTORM beginner!
