Molecular Devices SpectraMax M2 Microplate Reader SOLD 
Multi-Detection Reader and Dual-Mode Cuvette Port


SpectraMax M2 is a dual-monochromator, multi-detection microplate reader with a dual-mode cuvette port and 6-384 microplate reading capability. Detection modalities 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 M2 allows faster, more precise results and reagent savings. 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.
