Description
Molecular Devices SpectraMax GEMINI XPS Fluorescence Microplate Reader
Molecular Devices SpectraMax GEMINI XPS Fluorescence Microplate Reader is a monochromator-based fluorescence detection system designed for fluorescence intensity measurements across a broad range of research and analytical applications. The instrument utilizes tunable excitation and emission monochromators, allowing users to select virtually any wavelength combination without the need for dedicated optical filters.
The SpectraMax GEMINI XPS supports fluorescence assays used in molecular biology, cell biology, biochemistry, and drug discovery workflows. Its flexible optical design enables assay optimization for multiple fluorophores while supporting endpoint, kinetic, spectral scanning, and well-scanning measurements. The ability to adjust excitation and emission wavelengths independently makes the system particularly useful for assay development and custom fluorescence applications.
Common applications include DNA and RNA quantification, protein interaction studies, enzyme kinetics, calcium signaling assays, reporter gene analysis, fluorescence resonance energy transfer (FRET), cell viability studies, and high-throughput screening. The platform is widely used in academic, biotechnology, pharmaceutical, and life science research laboratories requiring sensitive fluorescence detection and wavelength flexibility.
