GATTA-BEADS

SMALL, BRIGHT AND CUTTING-EDGE. EXPERIENCE THE HIGHEST BRIGHTNESS DENSITY IN THE WORLD.

Fluorescent beads are important microscopy tools which can be used for calibration of microscopes, particle tracking 

or quantitative determination of point spread functions especially in STED microscopy. Particularly for the last point 

a small structure size keeping a high brightness is an immense advantage. Products from the GATTA-Bead series fulfill 

this requirement perfectly with a diameter of only 23 nm. Additionally, they show a clearly improved homogeneity and 

flexibility compared to other beads. We offer GATTA-Beads in the colors red (ATTO 647N), orange (ATTO 594), green

(ATTO 542) and blue (Oregon Green 488). Moreover, we offer alternative dyes which are indicated on the table below.

Additionally, we also offer 2-color beads in the color combinations red/orange, red/green and red/blue.

On request we can also design special solutions for your specific requirements. All samples will be delivered on a 

sealed glass slide which you can comfortably put directly on your microscope.

GATTA-BEADS - BRIGHTLINE

The GATTAquant Brightline series delivers you a much better tool for your experiments and calibration measurements

 we now developed a new series of GATTA-Beads featuring an even higher fluorescence brightness but without any 

loss of compactness compared to previous GATTA-Beads.

Currently we provide as colors orange (ATTO 594), yellow (ATTO 565), green (ATTO 542) and blue (Alexa Fluor 488 and

 Oregon Green 488) beads.

        Fields of Application：

           Setup calibration

           2D STED measurements                                                                      

           3D STED PSF distillation and deconvolution                         

           Tracking and drift-correction

       Advantages:

         Size: d = 23 nm

         Brightness: the highest brightness density

         Homogeneity: super small size and intensity distribution

         Flexibility: change color or add chemical groups
