显微镜中的荧光
荧光显微技术是一种特殊的光学显微镜技术。它利用的是荧光色素在一定波长的光激发下发光的能力。通过抗体染色或荧光蛋白标记,可以用这种荧光色素标记感兴趣的蛋白质。这样就可以确定单分子物种的分布、数量及其在细胞内的定位。此外,还可以进行共定位和相互作用研究,使用可逆结合染料(如 Ca2+ 和 fura-2)观察离子浓度,以及观察细胞的内吞和外吞过程。如今,利用荧光显微镜甚至可以对亚分辨率颗粒进行成像。

如何选择合适的测量显微镜
使用测量显微镜,用户可以测量样品特征的二维和三维尺寸,这对检测、质量控制、故障分析和研发&D 至关重要。然而,选择合适的显微镜需要评估应用需求以及显微镜的性能、易用性和灵活性。 如今,测量通常以数字方式进行,即使用带有摄像头和软件的显微镜,图像显示在显示器上,而不是通过目镜网线,从而提高了精度和可重复性。使用合适的测量显微镜可靠、快速地分析样品。
