Running an Experiment

Overview

This chapter provides a starting point for setting up and running a

kinetic cell-based assay on the FLIPR

Tetra System. Running an assay

requires performing the following tasks:

•

Preparing the cells

•

Powering-up the system

•

Running a system check

•

Dye-loading the cells

•

Preparing source plates

•

Setting up an assay protocol

These tasks are explained in detail in the remainder of this chapter.
Following the general procedures for running a FLIPR

Tetra System

experiment, protocols are outlined for four types of assays:

•

Fluorescence-based calcium mobilization

•

Fluorescence-based membrane potential

•

Fluorescence ratiometric membrane potential using Voltage

Sensor Probes

•

Luminescence-based detection of calcium mobilization

After the presentation of the assay protocols, guidelines for assay

optimization are provided.

Preparing Cells for Adherent Assays

Location of Cells in the Plate

The excellent signal-to-background noise ratio of the FLIPR Tetra

System is made possible by the instrument’s bottom illumination and

detection system. The read plate is illuminated by the LED modules at

an angle approximately 45. It is recommended to have cells located at

the bottom of the wells during an experiment. Adherent cells are

typically grown overnight in the cell plate, whereas non-adherent cells

are seeded either the night before, on a coated plate, or the day of an

experiment and then centrifuged.
