Calbryte™-520XL, potassium salt
Calbryte 520XL, potassium salt is a new fluorescent and cell-impermeable calcium indicator with extremely low affinity. It has Kd ~300 uM, which is the similar to the well-known Rhod 5N, but much more stable than Rhod-5N. Calbryte 520XL produces bright fluorescence signal in the presence of calcium ion in high concentration. It has the identical excitation and emission wavelength as Fluo-4, thus the same Fluo-4 assay settings can be readily applied to Calbryte 520XL-based calcium assays.
