使用安装框架进行光片样品准备

样品处理通常是光片显微镜研究中的一个关键话题。徕卡显微系统的TCS SP8 DLS将光片技术集成到倒置共聚焦平台中，因此可以利用关于样品安装和XY-stage功能的一般原则。本文将描述一组安装框架，这些框架不仅允许准备更多的样品，尤其是在使用诸如BABB（苯甲醇苯甲酸酯）等潜在有害的安装介质时，亦具有广泛的适用性。

如何通过激光显微切割改善您的 DNA 突变分析工作流程

DNA 突变导致异常蛋白质或缺失功能蛋白质，这可能导致细胞不受控制地增殖并变得癌变。为了找到并理解特定癌症类型的潜在突变，提取纯肿瘤材料是极其重要的。这尤其具有挑战性，特别是当只有有限数量的癌性组织可用时（例如小转移）。激光显微切割允许提取纯粹的癌性组织，而不会用健康细胞污染您的样本。DNA 测序将导致有效且可重复的结果，帮助轻松识别致癌的 DNA 突变，因为不会被污染的健康细胞掩盖。

使用旋转设备进行光片样本安装

TCS SP8 DLS 显微镜采用了一种创新的设计理念，将光片显微技术集成到共聚焦显微镜中。得益于其独特的光学架构，样本可以像进行标准共聚焦成像一样，安装在标准玻璃底培养皿上。与传统的样本安装程序相比，这一过程只需进行少量调整。
