This system is a benchtop flow cytometer that combines optical resolution and volumetric sensitivity. The system is required as it permits exact determination of size changes, whether it is diameter in microns or volume in cubic microns by measuring Coulter Volume. This system uses a mercury arc lamp to excite the cells in the UV range and can be used to examine a variety of UV-excitable dyes, including Hoechst and DAPI for DNA analysis, Indo-1 for calcium and PBFI and SBFI for potassium and sodium, and relate all these measurements to changes in cell size. All responsible sources may respond by submitting a written narrative statement of capability within 15 days of date of notice to Dee Lunney at the above address for consideration by the agency. Response must include detailed technical information and other technical literature demonstrating the ability to meet these requirements.
