| Description: | 1. Wash each well with 80 microL of assay buffer (20 mM HEPES, 1×HBSS, pH 7.4 adjusted with NaOH) three times and leave 20 microL using plate washer, ELx-405 Select CW (BIO-TEK).2. Add 20 microL of assay buffer containing 2.5 mM probenecid, 0.5 microM Fluo-4-AM (Molecular Probes) and 0.1% Pluronic F-127 to each well.3. Incubate the plate at 37° C. in 5% CO2 for 1 h.4. Wash each well with 80 microL of assay buffer (see below) three times and leave 20 microL using plate washer, ELx-405 Select CW (BIO-TEK).5. Test compounds were prepared at 100× the test concentration in DMSO by serial dilution with Biomek-FX liquid handling instrument. 33× diluted compound solutions in assay buffer were prepared in intermediate compound plate with Biomek-NX liquid handling instrument. A further 3× dilution occurred in below steps 6 and 7.6. Add 20 microL of 33× diluted compound solutions into each well and leave the plate for 10 min under the dark at room temperature.7. Measure activity by FDSS as follows:Set the assay plate on the stacker of FDSS.Start the detection of fluorescence intensity at 540 nm by 480 nm exicitation.After 30 seconds, add 20 microL of assay buffer containing 240 microM BzATP (final concentration 80 microM). |
