Advanced High-Resolution and Super-Resolution Microscopy Techniques for Investigating Chromatin Structure and Epigenetics.

Fluorescence microscopy has emerged as an indispensable tool for investigating chromatin structure and epigenetic states. This technique not only enables super-resolution imaging to unveil detailed localizations and structures but also offers precise quantitative capabilities for comparing variations across multiple conditions. In this chapter, we present a comprehensive guide to immunofluorescence methods, detailing two primary fixation protocols. Additionally, we describe the application of super-resolution spinning disc microscopy, emphasizing its utility in detecting nuclear and epigenetic markers.
