FLIPR Calcium 5, 4, & 3 Assay Kit comparison

Comparison of fluorescent signal response to calcium flux during acetylcholine agonism of Muscarinic M1 receptor in CHO M1 cells. This illustrates the signal-to-noise ratios offered by various FLIPR Calcium Assay Kits with quench technology. Combining the novel fluorophore and the proven quench technology of the FLIPR Calcium 4 Assay Kit, the FLIPR Calcium 5 Assay Kit shows higher signal to background ratio than prior kits.
