3D nanorulers from the GATTA-PAINT series are ideal resolution standards for any type of 3D localization-based super-resolution microscope. Due to the blinking kinetics provided by DNA-PAINT technology, the samples exhibit minimal photobleaching. Each sample consists of a tower structure on which two pairs of spots (40 nm apart in the xy-plane) are positioned 60 nm apart along the z-axis. This design allows users to assess the system’s axial (z) resolution.

We offer the GATTA-PAINT 3D Tower in red (ATTO 655) and yellow (Cy3B).
