Fluorescence microscopy
The Reginato lab operates the confocal facility featuring the Leica Laser Scanning Spectral Confocal Microscope TCS SP2 AOBS advanced image acquisition and analysis system. This system includes a UV laser, as well as standard argon, and helium neon lasers that can simultaneously image four different fluorophores. In addition, the microscope includes objectives of 20x, 40x, 63x, and 100x magnification.
In addition, the Department has an Olympus IX71 inverted epifluorescence microscope with MetaMorph/MetaFluor Imaging System, CoolSnap HQ Digital CCD camera, and DG4 Galvo-wavelength switcher as well as an Olympus AX70 Compound epifluorescence microscope with Spot RT Slider camera.

Structural Biology Center
Full understanding of molecules requires information about both structure and function. Structural analysis utilizes chemical and/or physical tools to unravel the links between the three-dimensional structure of a biologically important molecule (protein, DNA, or RNA) and its function.
We have been flooded with new information about the human genome. Translation of this information into structural information should rapidly lead to insights regarding function, which in turn are essential to the desired ultimate clinical applications. Now that we know that the precise regulation of cell function and organismic organization is accomplished by only 35,000 genes, it is clear that combinatorial processes must underlie the events controlling normal development and function and that aberrations in those control mechanisms are the root of disease. The molecular bases of these combinatorial events lie in protein-protein interactions; to properly understand them, it is essential to define these protein interactions at a three-dimensional level.

The Structural Biology Laboratories are housed within the Department of Biochemistry & Molecular Biology and are under the direction of Dr. Patrick Loll. The goal for the laboratories is to utilize a multifaceted approach to understanding structure/function relationships, in order to provide the structural information essential for understanding biologically important processes at the molecular level.
