Measuring thousands of wells in minutes, as needed for compound screens, requires extremely fast and sensitive instrumentation – the perfect task for BMG LABTECH plate readers.
An essential part of the early phase of drug discovery is screening libraries of compounds in order to detect potential ‘hits’ which interact with a therapeutic target. Common targets include membrane proteins such as GPCRs as well as kinases and PROTACS. Compounds acting on a therapeutic target have to be identified out of libraries of thousands to millions of compounds, making automation of the process using microplate readers essential.
Screens are mainly conducted in 384 and 1536 well plates to minimize reaction volumes per sample. Speed and sensitivity are key requirements for screeners. A 1536 well microplate needs to be measured in seconds, maximally a few minutes. Furthermore, the fast measurement of 10 µl or even lower volume samples needs to be very precise and stable to clearly identify hits from a vast number of compounds. In addition, the reader needs to be reliable, as errors occurring during a screen result in repetitions, loss of time, reagents and consequently money.
BMG LATBECH’s multi-mode microplate readers have market leading performance ensuring hits can be reliably detected at low volumes and at the fastest speeds. This not only enables the highest throughput but also allows rapid cycle times in kinetic assays required for studying binding kinetics and on/off rates.
The PHERAstar FSX masters all these requirements in all detection modes, making it popular in screening facilities. For screening assay development and testing, the CLARIOstar Plus is the perfect addition to develop and characterize an assay before transitioning to high throughput.
