From Light to Mind: Sensors and Measuring Techniques in Confocal Microscopy

This article outlines the most important sensors used in confocal microscopy. By confocal microscopy, we mean "True Confocal Scanning", i.e. the technique that illuminates and measures one single…

Video: The White Light Laser – How to Effectively Excite Multiple Fluorophores with a Single Light Source

The Leica White Light Laser produces a continuous spectral output between the wavelengths of 470 and 670 nm. It allows you to select 8 excitation lines from 3 trillion unique combinations for…

Joseph Gall的视频讲座：显微镜的早期历史

Joseph Gall带我们了解早期显微镜的历史和细胞的发现。复式显微镜是在17世纪与望远镜一起发明的；然而，由于光学畸变，这些显微镜直到19世纪末才被广泛使用。在此期间，简单的显微镜在整个18世纪和19世纪被用于生物学的重大发现，包括对细胞核、纤毛、细胞、细菌和原生动物的首次描述。光学技术在19世纪中后期得到改善厚，复合显微镜就被用来发现染色体、有丝分裂和其他细胞结构。

Workflows & Protocols: How to Use a Leica Laser Microdissection System and Qiagen Kits for Successful RNA Analysis

Laser Microdissection (LMD) allows isolating individual cells or chromosomes and is a well established technique for sample preparation prior downstream analysis of the nucleic acid content via PCR or…
