Key instrumentation

Labcyte Echo 555. The majority of compound library screens performed at IDAD rely on solvated compound dispensing by the Labcyte ECHO 555, an acoustic liquid handler. The ECHO uses acoustic energy to eject compounds from a source plate to the destination assay plate. Acoustic transfer occurs very quickly, allowing an entire 384-well plate to be transferred in 2-4 minutes (depending on volume), comparable to the time required for a conventional tip based instrument to load tips, aspirate, and dispense. The ECHO allows precise and accurate transfer of volumes as low as 2.5 nanoliters, and larger volumes through increments of 2.5 nanoliters. The airborne transfer of compounds from the source plate to a facing (inverted) destination plate prevents cross-contamination, and avoids the problem of liquids sticking to tips. The ECHO allows transfer of any source well to any destination well, so it can easily cherry-pick and perform serial dilutions and dose responses quickly, without a need for intermediate plates, and can dispense to any plate format, including 1536 and 3456-well plate formats.

Roche LightCycler® 480. The Lightcycler is used for performing rapid, accurate polymerase chain reaction (PCR) in combination with real-time, with online detection enabling absolute or relative quantification of a target nucleic acid, as well as post-PCR analysis of the amplified nucleic acid by Melting Curve analysis. The Lightcycler is used to perform high throughput screens based on measurement of changes in gene expression due to exposure of cells to small molecules or siRNA. Miniaturization of real-time reverse transcription polymerase chain reaction (RT-PCR) assays in 384 well format permits direct and rapid measurement of levels of the native biologically relevant mRNA expression in primary cells or cell-lines of interest.
