Enhancing Cryo-EM Resolution: The Impact of Agarose Gel Concentration on Sample Embedding
Cryo-electron microscopy (Cryo-EM) has revolutionized our power to visualize biological structures at near-atomic resolution. To achieve these remarkable feats, samples must be carefully embedded in a vitreous ice matrix. The choice of embedding medium, particularly the amount of agarose gel, can significantly influence the final quality of the resulting images. Higher agarose concentrations can hinder sample movement during freezing, leading to increased heterogeneity and reduced resolution. Conversely, lower concentrations may result in artifacts due to ice crystal formation or sample collapse.
Optimizing the agarose gel concentration is a critical step in achieving high-resolution Cryo-EM images.
- Careful optimization of the agarose gel concentration can minimize both sample movement and ice crystal formation during the freezing process.
- By balancing these factors, researchers can enhance the preservation of delicate biological samples for Cryo-EM analysis.
