Assay Kits

  • We offer a full line of assay kits optimized for use with the FLIPR Tetra System.



The FLIPR Tetra System supports numerous assay categories including:


  • GCPR assays: Calcium assay kits, Fura 2 QBT Calcium Assay Kit, LiveWare, Transfluor, cAMP assay
  • Ion channel assays: Membrane potential assay, Calcium assay, Potassium assay
  • Enzyme assay: cGMP assay
  • Transporter assays: Neurotransmitter transporter assay, Fatty acid uptake assay
  • Cardiotoxicity assays



FLIPR Tetra System utilizes Molecular Devices ScreenWorks® System Control Software to define and run experimental protocols. Using a drag-and-drop interface, protocols can be easily set up to include:

  • Fluorescent or luminescent read modes
  • Simultaneous transfer of 96, 384, or 1536 liquid or cells in suspension
  • Complex quadrant, multiple aspirations, or multiple dispensing liquid handling
  • Single or ratiometric kinetic cell-based reading
  • Tip washing with up to two solvents
  • Cell suspension delivery with automatable cleaning protocols
  • Simple-to-create automation protocols

ScreenWorks Software is both flexible and user-friendly. During protocol set-up, only relevant options are displayed, based on the installed fluidics and optics hardware, making it easy to choose parameters that are right for each assay. Live and information-rich data in 96-, 384- or 1536-well plate format is displayed while testing. Specific wells can be grouped for analysis or data export purposes. Graphs and tables can be easily copied and pasted into documents, presentations or worksheets, and different reductions can be selected for group statistics, making results readily accessible.

Optional Cell Suspension System  and Consumables
An optional cell management system for the FLIPR Tetra System simplifies luminescent calcium mobilization assays and increases throughput by eliminating the need to plate cells and the need for separate compound plates during aequorin assays. Cells are held in spinner flask which maintains a uniform cell suspension and promotes assay robustness. During the assay, cells are pumped to the reservoir for pipetting and returned to the spinner flask. Adjustable stir speed, pump speeds and pipetting parameters simplify the optimization of cell handling for different cell lines.  A variety of flask sizes are available to scale the volume for assay development through high throughput screening. Requires Part number 03010-5339 field installation of Cell Suspension system.
