Description Thumbnail
This Beckman Coulter XL-A analytical ultracentrifuge has been fitted with a fluorescence detector.
This fluorescence optical system is part of the AU-FDS (Analytical Ultracentrifuge Fluorescence Detection System) developed by CAMIS (the Center to Advance Molecular Interaction Science). The system is currently available through Aviv Biomedical. This system offers picomolar sensitivity, a dynamic range of several decades, and fluorescent selectivity. See our tutorial section for instructions on running a sedimentation velocity run with this system.
The AU-FDS control box provides a computer interface for the system. The attached Windows PC runs the AOS software (Advanced Operating System) by Tom Laue which provides a graphical user interface for controlling the AUC and recording data.
This is an example of a cell for an AUC sedimentation velocity run. Such cells and associated parts are available from Spin Analytical, Inc.
