GATTA-荧光小球

GATTA-荧光小球 / 超高分辨率STED显微镜测试工具

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

应用范围:

• 系统设置校准
• 2D STED测量
• 3D STED PSF 反卷积
• 跟踪及漂移校准

优势:

• 大小: 直径 = 23 nm
• 亮度: 高亮，高密度
• 高度均一: 超级小的尺寸及强度分布
• 灵活性: 颜色修改或者增加化学成分
