Correlative microscopy.

Area of Science:

• Cell biology
• Microscopy

Background:

• Correlative microscopy analyzes the same cell or tissue area using multiple microscopy methods.
• Traditionally, light microscopy (LM) and electron microscopy (EM) are performed on separate samples.
• LM offers global-scale and live imaging, while EM provides high resolution.

Purpose of the Study:

• To describe imaging using correlative light-electron microscopy (CLEM).
• To enable high-resolution EM imaging of structures observed with LM.
• To facilitate the study of rare or transient biological events.

Main Methods:

• Utilizing correlative light-electron microscopy (CLEM).
• Performing live imaging with LM followed by EM analysis of the same sample.
• Applying guidelines for CLEM imaging of organelles and cellular events.

Main Results:

• CLEM allows high-resolution EM imaging of structures previously observed with LM.
• Rare events captured by low-resolution LM imaging can be studied at high resolution by EM.
• Transient events observed via live LM imaging are amenable to subsequent high-resolution EM analysis.

Conclusions:

• CLEM bridges the gap between LM's live imaging capabilities and EM's high resolution.
• This method enhances the analysis of cellular structures and dynamic biological processes.
• CLEM provides a powerful approach for detailed investigation of cellular events.
