The Biochemistry Optical Core (BOC) provides state-of-the-art instrumentation for light and fluorescence based microscopy, including epifluorescence, confocal, and super-resolution imaging. Established by a faculty-approved investment from the Department of Biochemistry Endowment, our goal is to serve the campus research community by providing access to and training on basic and advanced light microscopy techniques.  Expertise and advice is available for the design of experiments involving these techniques.  

Open to All Academic and Industrial Researchers

Available Equipment Include

Nikon A1R-Si+ Confocal Microscope

Nikon SIM (Structured Illumination Microscope)

Nikon STORM/TIRF/epifluorescence Microscope

Offline Nikon Elements Analysis Stations



New Computer installed on the N-STORM system
