GATTA-熒光小球 / 超高分辨率STED顯微鏡測試工具

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
