Cell Biology Research

When your research is centered on understanding the cellular basis of human health and disease, it is critical to investigate the cells of interest in spatiotemporal and molecular detail. Consequently, microscopy is an ever-important tool in cell biology, allowing you to study your specimens in detail within their structural environment, as well as, analyze cellular organelles and macromolecules. Cell biology imaging is done with a range of light and electron microscopes. Imaging solutions offered by Leica Microsystems are designed to maximize your cell biology research.

Challenges with cellular imaging

The challenges faced when using microscopy for cell biology research vary, as the imaging of inter- and intra-cellular events requires a range of samples that vary in size and complexity. Imaging of these events needs to be performed from the nanometer to the millimeter scale.

Additionally, the study of cells under the microscope is further influenced by whether they are live or fixed samples, as these cases pose different imaging challenges. One challenge is how to capture fast dynamic events with the right resolution. Another one, for any cellular structures or events that do not produce a natural contrast during imaging, is choosing the right fluorescent proteins, antibodies, or nucleic acid probes to use as tags for specific proteins, DNAs, and RNAs in the cell to be viewed with fluorescence microscopy.

Finding the right solution for cellular imaging

Choosing the right microscopy method is critical if you want to maximize your research output and obtain the highest quality data.

Leica Microsystems offers various solutions to improve your cell biology research. These range from digital imagers that enhance daily cell culture tasks to high-end imaging solutions that enable the study of single molecules in detail or maximize the amount of results you get from your sample.
