Microplate Readers and Reader Accessories
Microplate readers are a type of spectrophotometer designed specifically for analyzing multiple samples in multi-well plates.
The readers detect light signals that result from biological, chemical, biochemical, or physical reactions. The signals are produced by, converted by, or transmitted through the samples and are measured by a detector. The detectors are usually photomultiplier tubes (PMT), which convert the released photons into electricity. The current is quantified by the reader’s software to produce the numerical result.
In some cases, samples are first excited by exposure to light of specific wavelengths. Filters or monochromators are used to select or restrict the wavelengths needed for emission or detection.
Single-mode microplate readers commonly measure absorbance, fluorescence, or luminescence. Multi-mode plate readers may measure absorbance, fluorescence, and luminescence with options for fluorescence polarization (FP). They may also include lasers for time-resolved fluorescence (TRF), TR-FRET, Amplified Luminescent Proximity Homogeneous Assays (ALPHA), and cell imaging.
Features may include:
- Monochromator- or filter-based wavelength selection
- Visible only or UV/Vis spectrum, fluorescence, and luminescence
- Multiple photomultiplier tubes (PMTs) for simultaneous assays
- Temperature and CO2/O2controls
- Modular design for adding functionality
Microplate readers are used for high-throughput screening (HTS), biomarker assays, nucleic acid and protein quantification, kinetics, ELISA assays, homogeneous time resolved fluorescence (HTRF) for measuring cytokines, bioluminescence resonance energy transfer (BRET), and other techniques.

Sigma Aldrich Fine Chemicals Biosciences TranscreenerR ADP2 TR fRET
The Transcreener(R) ADP2 TR-fRET Red Assay is a competitive immunoassay for ADP with a far-red time-resolved foumlrster-resonance-energy-transfer (TR-fRET) readout. Because it is highly selective for ADP the assay can be used with any enzyme that converts ATP to ADP regardless of what other substrates are used. Examples of enzymes include protein lipid and carbohydrate kinases ATPases DNA helicases carboxylases and glutamine synthetase. The Transcreener(R) assay is designed specifically for high-throughput screening (HTS) with a single addition mix-and-read format. It offers reagent stability and compatibility with commonly used multimode plate readers. The generic nature of the Transcreener(R) HTS assay platform eliminates delays involved in assay development for new HTS targets and greatly simplifies compound and inhibitor profiling across multiple target families. The Transcreener(R) ADP2 TR-fRET Red Assay provides the following benefitsbullnbsp Accommodates ATP concentra
