Microplate Readers

As many of you know, microplate readers are instruments used to detect biological, chemical, biochemical or physical events from samples in a microplate. This is where it all starts for your basic research, assay development and therapeutic research. A powerful and reliable plate reader is what you need for your scientific breakthroughs or delivering new drugs and therapeutic treatments to market. It is a crucial component and workhorse for every lab to identify the ideal drug compound to advance it from discovery to development to manufacturing.

Industries that can benefit:

  • For academia – the need for all major detection technologies to run everyday biochemical and cell-based assays
  • For pharmaceutical, biotechnology and clinical research organization – the need for high sensitivity, speed, and throughput to perform complex assays with the desire to customize for automation

Configurable Multimode Plate Readers to Future Proof Your Lab

Multimode plate readers have become very popular. Market demand has driven instrument manufacturers to progress from producing single-mode plate readers to those with multiple modes of detection. They offer flexibility and savings in cost and precious lab space, together with the convenience of employing only one instrument versus having to purchase multiple dedicated instruments.

Our multimode microplate readers offer all major detections such as Absorbance, Alpha, Luminescence, Fluorescence Intensity, Fluorescence Polarization, and Time-Resolved Fluorescence, all in one instrument. In addition to the detection technologies, our EnSight multimode plate reader also offers fast well-imaging so you can perform target-based and phenotypic screening to gain valuable insights from different perspectives. All of our plate readers are configurable so you can add technologies when you need to future proof your lab. They are ideal for applications such as cell viability/proliferation/toxicity, drug screening, pathway analysis, receptor panning, biomarkers, protein:protein interaction, gene expression, food monitoring, and epigenetics.

PerkinElmer’s portfolio of plate readers is equipped with the latest detection technologies to meet the diverse assay requirements of labs today. With over 30 years of experience in instrument development, you can expect performance and reliability from any of our microplate readers.

Types of Detection Technologies


Well-Established Assay

Absorbance is the measurement between the amount of light being absorbed by a sample and the light that passes through the sample (non-absorbed). A specific wavelength of light is usually selected from an optical filter or the whole spectrum can be captured using a spectrometer. It is one of the most well-established microplate assay formats and perfect for assays such as ELISA, protein and nucleic acid quantification, and enzyme activity.


Assay for Virtually Any Application

Alpha is a high-performance laser-based technology, validated for use with our proprietary AlphaScreen® and AlphaLISA® assay kits. It has the power to assay the most complex samples – all in one well, with no wash steps. Alpha Technology enables fast, simple, highly sensitive detection of biomolecules in cell lysates, cell supernatants, serum, and a variety of other sample types. Laser-based Alpha detection allows you to have quick readouts, while maintaining a high signal-to-background ratio.


Ideal for Reporter Gene, Cytotoxicity, and Proliferation Assays

Luminescence is the measurement of light emitted as a result of a chemical or biochemical reaction with no excitation energy. A luminescence assay is extremely useful as a detection platform because of its wide dynamic range, greater sensitivity than fluorescence technologies and lower interference than other detection options. Luminescence assay formats include glow and BRET, and flash or dual glow – perfect for applications such as reporter gene, cytotoxicity, and proliferation assays.

Fluorescence Intensity

Popular Light Emission Detection

Fluorescence Intensity is the measurement of light emitted from a molecule (fluorophore) at one wavelength and light excited at a shorter wavelength. It is one of the most popular detection modes, and there are innumerable fluorophores available for applications such as DNA or protein quantitation, reporter-gene expression, and protein binding.

Fluorescence Polarization

Ideal Detection for High Throughput

Similar to Fluorescence Intensity, Fluorescence Polarization is based on the emission of light by an excited fluorophore. For this detection, samples are excited by polarized light using specific filters. It is generally applied to measure binding events between small and large molecules. Fluorescence Polarization is a homogeneous assay technology that’s ideal for high-throughput screening. Fluorescein is the commonly used fluorescent label and is suitable for typical applications such as receptor-ligand binding, protein interaction, or hapten immunoassays.

Time-Resolved Fluorescence

Enhanced Sensitivity and Dynamic Range for Immunoassays

Time-Resolved Fluorescence (TRF) uses fluorescent molecules, called lanthanides, that can emit light over long periods of time after excitation. Time-Resolved Fluorescence can help improve the sensitivity and dynamic range of your immunoassays, even when sample is at a premium or in low concentration. TRF detection, together with lanthanide-based DELFIA, LANCE Ultra, or HTRF chemistries, offers enhanced signal-to-background ratio, high sensitivity, wide dynamic range, superior stability, and excellent flexibility.

A microplate is a critical part of your discovery process. Microplates have the capability to generate valuable, information-rich data that bring great insights into discovery screening.

Microplate planarity and inaccurate data collection are common issues caused by microplates that are not carefully designed for the unique challenges of sample screening which can result in missed data points, sample re-screening, missed project timelines, and ultimately higher costs.
