GATTA-STED 3D Nanoruler

GATTA-STED 3D Nanoruler

Being the first super-resolution microscopy technique the STED method revolutionized the light microscopy. With the nanorulers from the GATTA-STED series now adequate calibration probes are finally available. GATTA-STED 3D 90R Expert Line nanorulers are single color 3D structures carrying two fluorescent marks out of a dense arrangements of the high quantum yield dye ATTO 647N. The spots are separated by 90 nm and oriented in axial direction.

The 3D nanorulers are intended for use with high-performing STED systems with extraordinary z resolution and are only recommended for very experienced users.

On request we can also design special solutions for your specific requirements. All nanoruler samples will be delivered on a sealed glass slide which you can comfortably put directly on your microscope.
