FDSS®-GX 动态板成像仪
FDSS-GX 是 FDSS 系列中性能最高的动态板成像仪,针对 96 孔、384 孔和 1536 孔进行了优化,可实现可靠而又稳定的高通量筛选 (HTS),从而实现整个微孔板成像和同时向所有孔进样。该系统使用 qCMOS 传感器实现高灵敏度成像,并通过采用能够分配可变体积的 1536 通道分配装置,实现高精度和可重复的微量分配。通过组合可选部件,可以根据用户的目的构建无机器人半自动化系统。
FDSS是日本滨松光子学株式会社,及其全球子公司(中国大陆、法国、德国、意大利、日本、英国、美国)注册使用的商标。
分配准确性和可重复性是进行分析的重要因素。
FDSS-GX 通过采用能够分配可变体积的 1536 通道分配装置,实现了高精度和可重复的微量分配。该分配装置具有专用于 FDSS-GX 的独立金属活塞缸和分配头。
还提供 96 通道和 384 通道的分配装置。

下图显示了将 B 珠分配到 1536 微孔板(5 µL/孔)中时荧光强度随时间和板图像的变化,显示分配后的 CV 为 1.89%。
1536 通道分配装置带有独立的金属活塞缸和专用于 FDSS 的分配头,提供最佳的分配性能。
*这是使用经过检修或校准的 1536 通道分配装置和专用于 FDSS-GX 的分配头分配 B 珠(5 µL/孔)时的实际测量值。
高灵敏度 qCMOS 传感器是 FDSS-GX 光学系统的标准配置。
在荧光和发光测量中,低光成像实现了高定量性能,并且由于传感器的宽动态范围,检测窗口已经扩大,从而实现了宽线性范围的测量。
此外,由于传感器尺寸大,qCMOS 传感器可以对整个板进行成像,并实现高分辨率测量。
在荧光测定中,FDSS-GX 能够检测 0.03 nM 荧光素*(曝光时间:50 ms)。
下图显示了荧光素滴定浓度的荧光计数和信噪比,图像显示了 384 微孔板。
* 这是实际测量值。
