| | FLIPR or FLIPRTETRA Sodium Dye with KCl Assay |
| Description: | Cells were prepared by plating the recombinant HEK293 cells or other host cells expressing either recombinant or non-recombinant, native, Nav1.7 alpha subunit, alone or in combination with various beta and gamma subunits at a density of 40,000 cells/well into a 96-well black, clear-bottom, PDL-coated plate. The assay can be adapted to 384-well or 1,536-well format, if desired, using proportionately less cells and media. The plate was then incubated in growth media, with or without selective antibiotic, overnight at 37 C. at 5% CO2, 95% humidity, in preparation for the assay. For counter-screens of other voltage-gated sodium channels, the procedure was very similar, though optimal densities of cells, media and subsequent assay components can be fine-tuned for the particular cell line or isoform.The next day, at the start of the assay, the media was flicked from the cells and the wells were washed once with 50 ul/well assay buffer. |
