SXT offers high-resolution images without the need for staining or sectioning, allowing for real-time observation of biological processes in their native state.
What are the benefits of using cryo-preserved samples?
Cryo-preservation allows for the imaging of samples in a hydrated state, preserving their natural structure and integrity.
Can SXT be used in conjunction with other imaging techniques?
Yes, SXT can provide complementary data when used alongside other microscopy methods.
What is the significance of achieving 25 nm resolution?
Achieving 25 nm resolution allows researchers to observe fine details of cellular structures that are crucial for understanding cellular functions and diseases.
How quickly can tomograms be collected using SXT?
Tomograms can be collected in just a few minutes, making SXT a high-throughput imaging technique.
What types of biological questions can SXT help address?
