Time resolved applications for Cryo-EM; approaches, challenges and future directions.

Area of Science:

• Structural Biology
• Biophysics
• Biochemistry

Background:

• Cryo-electron microscopy (cryo-EM) has advanced to provide high-resolution static molecular structures.
• Capturing dynamic or transient molecular conformations has remained a challenge.

Purpose of the Study:

• To provide an overview of emerging time-resolved cryo-EM approaches.
• To discuss the strengths, limitations, and challenges of these novel techniques.

Main Methods:

• Overview of various time-resolved cryo-EM methodologies.
• Analysis of techniques for trapping non-equilibrium states within millisecond timescales.

Main Results:

• New approaches allow trapping and analyzing transient molecular states.
• Identified challenges in achieving higher resolutions and faster time-framing.

Conclusions:

• Time-resolved cryo-EM is a valuable addition to the cryo-EM toolkit.
• These methods expand possibilities for both single particle and tomographic studies.
