Being the first super-resolution microscopy technique, the STED method revolutionised light microscopy. With the introduction of the GATTA-STED series of nano rulers came the availability of adequate calibration probes for the first time. The single colour nanorulers carry two fluorescent marks out of dense arrangements of the high quantum yield dye ATTO 647N. GATTAQuant offer mark-to-mark distances in the following sizes: 50 nm, 70 nm, 90 nm and 120 nm. They also offer a new design containing three emitting points with two different fluorophores, which allows the acquisition of very eye-catching images. The multicolor nanoruler with three emitting points is available with the size of 140 nm (ATTO 647N & ATTO 594).
On request GATTAQuant can also design special solutions for your specific requirements. All nanoruler samples will be delivered on a sealed glass slide which are designed to be easily mounted directly on to your microscope.
