Instrumentation

High Throughput Screening Equipment

To request training on instruments, contact Martha Larsen.   In addition to providing small molecule libraries, the screening facility has the following equipment and resources available:

 

  Sciclone ALH3000 with a V&P pintool, delivery of 50-80 nl volumes; can be used with 1536-well plates; uses Twister plate hotel to deliver source plates.
   
   
Envision Multimode Plate Reader (Perkin Elmer), two detectors enabling simultaneous dual wavelength reading; enhanced luminescence; Alpha capabilities (AlphaScreen and AlphaLisa); Stackers for automatic plate reading; FP, FI, TR-FRET, Abs, BRET, HTRF; cross talk, calibration and normalization features; Kinetic reads.
   
  Mosquito X1 (TTP Labtech), a hit-picking liquid handler with 96- and 384-well plate formats, 25-1200 nL positive displacement tips for confirmation, serial dilutions and reagent/sample transfers.
   
MDS Analytical Technologies-ImageXpress Micro Cellular Imaging and Analysis System for automated acquisition and analysis of images for high throughput cell-based screening.  Includes Acuity Xpress Informatics and MDCStore database. Several plate options (6-384-well) and slide mounts are available for high content analysis and screening.
   
Biomek FX dual head (Beckman): A programmable robot, utilizing both disposable tips and HDR (pin tool) to rapidly transfer compounds from library stock plates to assay plates. 96 and 384-well plate capability.
   
  Biomek FX (Beckman) 384-well nanoliter HDR (pin tool)
   
Hypercyt/Accuri : High Throughput Flow Cytometer combination system that does multiplex flow cytometry on 384-well plates (~ 10 min/plate).  Used for both cell- and bead-based HTS.
   
Plate reader: PHERAstar (BMG Labs) with luminescence, fluorescence, fluorescence polarization, time-resolved fluorescence and absorbance detection methods with 96 and 384-well plate capability. Sample sizes from 5-200ul.

Pherastar Modules:

  • Luminescence (1 channel)
  • Fluorescein/FITC (485/520)
  • FP-Fluorescein/FITC (485/520A/520B)
  • FP-TAMRA (540/590A/590B)
  • AMC (350/450)
  • AMC2 (370/480)
  • TR-FRET (337/520/490)
  • FP-Texas Red (575/620A/620B)
  • Absorbance (450)

Other filter modules available request a list from Martha Larsen

FlexStation3 (MD) plate reader that is capable of reading 5 assay formats for kinetic, endpoint, spectrum, well-scanning and “Flex.”.
   
Plate Handler: Twister (Caliper Life Sciences) microplate handler allows for automated integration of liquid dispensers, plate washers, and other HTS assay components during screening creating a stand alone module.
   
Bio-Tek ELx405 plate washer/aspirator with 96 to 384-well capability.
   
Thermo Labsystems Multidrop plate dispensers with 96 and 384-well capability.

Tissue culture facilities. Multichannel pipettors.
