The SpectraMax® L microplate luminometer from Molecular Devices offers the sensitivity, reliability, flexibility, upgradability, automation options, and validation tools required by today's leading laboratories. The system is ideal for measuring flash and glow assays, including dual luciferase reporter gene, G protein-coupled receptor (GPCR) via aequorin, bioluminescence resonance energy transfer (BRET), and acridinium ester flash assays, in both 96- and 384-well plates. The SpectraMax L system is upgradeable to multi-channel configurations for a 6-fold increase in throughput for medium throughput and secondary screening laboratories. Industry-leading SoftMax® Pro software eliminates the need to export data to spreadsheet programs, and manages instrument control and results generation in a GxP environment. SoftMax Pro GxP software and its software validation package provide comprehensive documentation and extensive data sets in CD-ROM format to meet FDA 21 CFR Part 11 and GxP compliance requirements.

Reduce Noise

Ultra-fast photon counting technology amplifies the PMT signal with a fast pulse amplifier. This reduced noise capability enables a higher signal-to-noise ratio and the lowest crosstalk in laboratory assays.

Nine Orders of Dynamic Range

The MaxRange simultaneous analog and photon counting capability provides a dynamic range of more than nine orders of magnitude, eliminating the need to dilute bright samples while maintaining excellent sensitivity for dim samples.

Up to 6-Times Faster

The SpectraMax L is available in 1-, 2-, and 6-channel (Photomultiplier Tube) configurations. The 6-channel configuration is available with 0 or 12 injectors for a 6-fold increase in throughput for flash and glow assays including GPCR via aequorin (Figure 1) and dual luciferase reporter gene screening.

The 2-channel configuration is available with 0, 2, or 4 injectors. The 4 injector configuration enables flash and glow BRET assays and a 2-fold improvement in speed for traditional flash and glow assays. The 2-injector configuration enables flash and glow BRET assays, a 2-fold increase in speed for traditional glow assays, and normal speed for traditional flash assays. The 0-injector configuration enables BRET assays and a 2-fold increase in speed for traditional glow assays.

Automatic And Manual PMT Calibration

The SpectraMax L system offers two methods to correct inherent PMT spectral response variability in multi-channel configurations. The automatic PMT calibration method is based on readings of 4 internal LEDs at 395, 470, 527, and 570 nm. Figure 2 shows the PMT to PMT precision for wells of various intensities read by 6 individual PMTs calibrated with the LED-based method. The manual PMT calibration method is based on readings of 4 wells from the assay itself.

Precise And Reliable Autowashing Injectors

The SpectraMax L system's next-generation injectors enable better results and more robust performance over current offerings. For example, to prevent precipitation from clogging injector lines, the lines must be rinsed of reagents when the instrument is idle overnight. The system features a unique AutoWash function that can be programmed to rinse the injectors following each use of the instrument, and the direction of flow can be reversed so reagents can be recovered before the rinsing is started. Furthermore, the automatic injection counter sends an alert when 75 million µL have been injected to indicate when minor injector maintenance is due.

Easy-To-Use, Industry-Leading Software

Instrument control, data collection and data analysis are managed through SoftMax Pro software. Data can be analyzed using predefined or custom formulas. Results are displayed in each well of the microplate. Graphs are easily plotted and labeled using the graphing function. (See Figure 3.)

Integrated Stacker and Robot Compatibility

Molecular Devices offers the StakMax® microplate stacker for use with the SpectraMax L system. (See Figure 4.) Landscape and portrait positions provide flexibility for optimum use of deck space when integrating with third-party liquid handling robots.
