The Gemini™ XPS Microplate Spectrofluorometer from Molecular Devices provides a flexible environment to determine the optimal excitation and emission settings for most fluorescent intensity assays. The Gemini XPS Reader has dual monochromators that allow users to utilize new and novel dyes without purchasing expensive filter sets. SoftMax® Pro Software, included with every Gemini XPS Reader, provides convenient data analysis. The optional SpectraTest® FL1 Validation Plate automatically validates the performance of the reader. Software validation, IQ/OQ/PQ and FDA 21 CFR Part 11 compliance tools are also available.
With the Gemini XPS Reader, users don’t have to worry about having the right set of filters. The system uses two scanning monochromators to determine the optimal excitation and emission settings. Assays vary depending on temperature or pH conditions; the monochromators allow users to select the optimal wavelength for any assay. Alternatively, literature values for the monochromator can be easily entered. When methods or fluorophores change, it takes only a few software commands to adjust the reader.
With well scanning, multiple points within each well can be read, providing a high level of sensitivity for cell-based assays. Endpoint, kinetic and spectrum scanning assays can also be run.
Plate stacker and robot integartion
The Gemini XPS Reader can be integrated with Molecular Devices’ StakMax® Microplate Stacker in a matter of minutes and begin reading microplates with seven mouse clicks. For a higher degree of automation, the Automation Vendor Partners Program has streamlined the integration of our microplate reader systems with all leading partner robots. The “out-of-the-box” automation solution saves up-front integration time and resources.
Leading data analysis software
SoftMaxt Pro Microplate Data Analysis Software provides flexibility in experimental design, setup, analysis and reporting, providing the opportunity to customize assays. Choose from nine different curve-fitting routines and use default data reduction, or set up custom formulas for analysis. Data can be analyzed and combined from different plates.
