What's Popular in Microplate Technology? 2011 Survey Results

The microplate has evolved over the past 60 years into an indispensable piece of equipment used in many labs today. In 2007, HTStec estimated market growth of microplate instruments at about 6 percent per year, with an average high-throughput system costing anywhere from $65,000 to $110,000. (Note: simple absorbance readers for individual plates cost significantly less). Large pharmaceutical and biotech companies purchased 23 percent of systems, academic labs 25 percent, and small pharma/biotech 52 percent.

Microplates have become common lab ware in life science and medicine. Sixty-one percent of the labs surveyed use microplate technology; another 11% plan to make a first-time purchase within the next 12 months.

For a laboratory involved in routine assay development and screening, achieving higher throughput depends on the ability to process multiple batches of assay microplates accurately and swiftly. Vendors offer systems for high-throughput primary screening, where labs need to process a large number of microplates, as well as for secondary screening, where labs process a large number of different assays.

Microplate reader detection modes define the instrument’s experimental capabilities, while the optics determine spectral selectivity. Detection modes include top- and bottom-read fluorescence, fluorescence polarization, time-resolved fluorescence (TRF), time-resolved fluorescence energy transfer (TR-FRET), AlphaScreen, absorbance and luminescence. Absorbance and fluorescence intensity constitute more than half of all applications.

Automated, unattended, reliable operation seems to be what most users demand from their microplate management systems. In order to drive down reagent costs, most labs in industry have migrated from screening in a 96-well format to screening in a 384-well format. A few have also moved to an even more miniaturized platform, using 1,536 wells.

To increase microplate capacity, labs are integrating two or more instruments. Laboratory equipment vendors may sell stand-alone microplate instruments, but most labs prefer purchasing the robotics already integrated with readers, stackers and other instruments.

Flexibility (available detection modes), performance (sensitivity, throughput) and cost are prime considerations in microplate reader selection, although the order of preference may differ for each market. Pharmaceutical screeners typically value throughput as their top criterion, while academic researchers may be more satisfied with lower throughput but high flexibility, particularly if it means a lower overall cost. Additional things to consider in making a purchase: The number of people who will be using the instrument, and your desired throughput; the number of parameters required for read-out; whether or not the assays will have an endpoint; whether or not the results will be acquired over a time course; and the desired plate format, as plates can range from 96 wells up to 1,536 wells.
