Example protocol
PREPARATION OF STOCK SOLUTIONS
Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles
Prepare a 2 to 5 mM stock solution of Fluo-5F AM in high-quality, anhydrous DMSO.
PREPARATION OF WORKING SOLUTION
On the day of the experiment, either dissolve Fluo-5F AM in DMSO or thaw an aliquot of the indicator stock solution to room temperature.
Prepare a 2 to 20 µM Fluo-5F AM working solution in a buffer of your choice (e.g., Hanks and Hepes buffer) with 0.04% Pluronic® F-127. For most cell lines, Fluo-5F AM at a final concentration of 4-5 μM is recommended. The exact concentration of indicators required for cell loading must be determined empirically.
Note: The nonionic detergent Pluronic® F-127 is sometimes used to increase the aqueous solubility of Fluo-5F AM. A variety of Pluronic® F-127 solutions can be purchased from AAT Bioquest.
Note: If your cells contain organic anion-transporters, probenecid (1-2 mM) may be added to the dye working solution (final in well concentration will be 0.5-1 mM) to reduce leakage of the de-esterified indicators. A variety of ReadiUse™ Probenecid products, including water-soluble, sodium salt, and stabilized solutions, can be purchased from AAT Bioquest.
SAMPLE EXPERIMENTAL PROTOCOL
Following is our recommended protocol for loading AM esters into live cells. This protocol only provides a guideline and should be modified according to your specific needs.
- Prepare cells in growth medium overnight.
On the next day, add 1X Fluo-5F AM working solution to your cell plate.
Note: If your compound(s) interfere with the serum, replace the growth medium with fresh HHBS buffer before dye-loading.
Incubate the dye-loaded plate in a cell incubator at 37 °C for 30 to 60 minutes.
Note: Incubating the dye for longer than 2 hours can improve signal intensities in certain cell lines.
- Replace the dye working solution with HHBS or buffer of your choice (containing an anion transporter inhibitor, such as 1 mM probenecid, if applicable) to remove any excess probes.
- Add the stimulant as desired and simultaneously measure fluorescence using either a fluorescence microscope equipped with a FITC filter set or a fluorescence plate reader containing a programmable liquid handling system such as an FDSS, FLIPR, or FlexStation, at 490/525 nm cutoff 515 nm.
