Confocal Microscopy Core
The Department of Biology at Saint Louis University offers a Leica SP8 confocal microscope with resonant scanner for academic and commercial use. Live-cell imaging can be performed using a stage incubator with programmable gas (O2, CO2 and N2) and temperature controls.

Zoomed in Microscope
The instrument features 405, 488, 522 and 645 nm diode laser lines, which allow for imaging of most fluorescent dyes with its two HyD and two PMT detectors. The instrument must be reserved on the lab agenda before using.
Live-Cell Imaging Capabilities
An OkoLab stage incubator with variable and programmable CO2 (0-10%), O2, N2 and temperature controls (4-40 degrees Celsius) can be used for a variety of cell and tissue culture-based studies under normoxic, hypoxic and hypercapnic conditions.
Image Analysis Capabilities
Image analysis capabilities include Lightning deconvolution, colocalization, 3D reconstruction, FRAP and FRET. A separate image analysis workstation with the Lightning and Colocalization modules is free to all users.
Hourly Rate for Use Effective 1/1/2024
- Approved user within the biology department: $35/hr
- Approved user from outside the biology department: $35/ hr
- Training sessions for new users within and outside of the biology department: $ 50/hr. Basic training requires at least two hours on the microscope. However, additional training may be required following assessment of the new user’s ability to properly operate the SP8 Leica Confocal Microscope. In addition, the passing of a short quiz is mandatory.
Note: Retraining is required for any user that has not used the microscope in three months from their last use at no charge
