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 23nm. 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
