眼部出生缺陷研究
本文讨论如何使用快速采集的宽场显微镜图像研究晶状体的形成和眼部出生缺陷。将小鼠晶状体用作模型,以研究眼睛细胞形态发生及细胞过程如何中断并导致发生缺陷。通过无模糊或离焦模糊的图像揭示了小鼠晶状体玻片内部深处的细节。这些图像是使用THUNDER Imager 3D Assay采集的。

为活细胞成像创造新选择
对厚实的活体样本进行成像时,主要挑战之一是获得图像质量与组织完整性之间的平衡。长时间的图像采集期间,弱信号光会导致低信号水平,导致图像对比度低以及分割和分析困难。需要通过高剂量成像或高时间分辨率成像技术加强信号强度时,这一问题更加突出。一个常见问题是:我如果快速成像、一次完成,会不会造成样本过度漂白或者细胞死亡?

精确分析宽视野荧光图像
利用荧光显微镜的特异性,即便是使用厚样品和大尺寸样品,研究人员也能够快速轻松地准确观察和分析生物学过程和结构。然而,离焦荧光会提高背景荧光,降低对比度,影响图像的精确分割。THUNDER 与Aivia 的组合可以有效解决这一问题。前者可以消除图像模糊,后者会使用人工智能技术自动分析宽视野图像,提高操作速度和精确性。下面,我们来详细了解下这一协作方法。
