Instrumentation:

Nikon A1R Confocal Laser Scanning Microscope

Fully automated A1 offers standard paired galvanometers with high resolution scanning at up to 4096 x 4096 pixels. The A1R model incorporates a hybrid scanner system utilizing a high speed resonant galvanometer capable of acquisitions up to 240 frames per second. Both scanners can be used simultaneously for experiments requiring acquisition and photoactivation by concurrently scanning the specimen. This supports advanced research methods using photoactivation fluorescence proteins and facilitates high-speed, live-cell work with a huge array of new imaging strategies. A spectral imaging detector further enables the A1 and A1R models to obtain up to 32 discreet spectral bandwidths of data in one acquisition, with spectral unmixing capabilities. The total system is controlled through NIS-Elements C applications software, which also enables full control of the Nikon Ti-E research inverted microscope equipped with Nikon's Focus System (PFS), widefield CCD cameras and an array of hardware devices.

Description:

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.
