Molecular Devices Spectramax M5 w/cuvette port
Absorbance, Fluorescence, FI, TRF, Polarization and Luminescence Reader
Multi-Detection Reader and Dual-Mode Cuvette Port


Spectramax M5 is a dual-monochromator, multi-detection microplate reader with a dual-mode cuvette port and 6-384 microplate reading capability. Detection include absorbance (UV-Vis Abs) and fluorescence intensity (FI) and have optical performance comparable to a top-of-the-line dedicated spectrofluorometer or spectrophotometer. Endpoint, kinetic, spectrum and area-well scanning read types and PathCheck® allow homogeneous and heterogeneous microplate assays to be performed in this flexible system. The FI and Abs microplate reader with built-in cuvette port allows easy conversion and optimization of very-low-throughput assays into medium-high-throughput microplate assays. The SpectraMax M5e allows faster, more precise results and reagent savings and is the top of the line instrument. In addition, combined absorbance and fluorescence intensity assays can be run by issuing a single read command.

Compound Profiling Assays

Spectramax microplate readers are ideal for increased throughput of early ADME compound profiling assays such as the Transil® Membrane Affinity assay and Human Serum Albumin Binding assay. The Membrane Affinity assay provides high-throughput lipophilicity data equivalent to liposome-based methods without the need for ultracentrifugation. The Human Serum Albumin Binding assay provides high-throughput blood protein binding data by measuring the fraction bound to Human Serum Albumin.
