Area of Science:

• Cell Biology
• Biophysics
• Microscopy Techniques

Background:

• Xenopus laevis egg extracts are traditional tools for biochemical assays.
• Live imaging with time-lapse microscopy enhances understanding of cytoplasmic dynamics.
• Existing live imaging methods often require complex surface treatments for vessels.

Purpose of the Study:

• To introduce a novel, simplified method for live imaging of Xenopus laevis egg extracts.
• To present a technique that avoids chemical surface treatments and uses common lab consumables.
• To enable detailed study of cytoplasmic phenomena using wide-field and confocal microscopy.

Main Methods:

• A new system for live imaging of Xenopus laevis egg extracts is described.
• The method requires no chemical surface treatment of imaging vessels.
• It utilizes mass-produced laboratory consumables and is compatible with wide-field and confocal microscopy.

Main Results:

• The method allows for live imaging of cytoplasmic dynamics in Xenopus laevis egg extracts.
• Representative data demonstrate the dynamic organization of microtubules, nuclei, and mitochondria.
• Quantitative information on cytoplasmic dynamics and spatial organization can be obtained.

Conclusions:

• This new method offers a simple and accessible approach for live imaging of Xenopus laevis egg extracts.
• It facilitates the study of spatial pattern formation and dynamic organization within the cytoplasm.
• The technique can be extended for 3D imaging and provides valuable quantitative data.
