Description

Description: Calcium flux assays are the preferred methods in drug discovery for screening G protein coupled receptors (GPCR). Screen Quest™ Calbryte-520 Probenecid-Free and Wash-Free Calcium Assay Kit provides the most robust homogeneous fluorescence-based assay for detecting the intracellular calcium mobilization. Cells expressing a GPCR of interest that signals through calcium are pre-loaded with our proprietary Calbryte™-520NW which can cross cell membrane. Calbryte™-520 NW is the brightest calcium indicator available for HTS screening. Once inside the cell, the lipophilic blocking groups of Calbryte™-520NW are cleaved by non-specific cell esterase, resulting in a negatively charged fluorescent dye that stays inside cells, and its fluorescence is greatly enhanced upon binding to calcium. When cells stimulated with screening compounds, the receptor signals release of intracellular calcium, which greatly increase the fluorescence of Calbryte™-520NW. The characteristics of its excellent cell retention, high sensitivity, and 100-250 times fluorescence increases (when it forms complexes with calcium) make Calbryte™-520NW an ideal indicator for measurement of cellular calcium. Calbryte™-520NW is the only calcium dye that does not require probenecid for better cellular retention. This Screen Quest™ Calbryte-520 Probenecid-Free and Wash-Free Calcium Assay Kit provides the most optimized assay method for monitoring G-protein-coupled receptors (GPCRs) and calcium channels with fragile or difficult cell lines. The assay can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation.
