DETAILS

Description (English)
Application
suitable as Ca2+-indicator (fluorescence suppressed by Ca2+)
BAPTA-Na4 is a fluorescent compound utilized to determine free Ca2+ by performing fluorescence emission scans at an excitation wavelength of 299 nm and measuring the emission wavelength at 360 nm 1,2,3.
Other Notes
Chelator with a greater selectivity for calcium compared with magnesium (spectrophotometric monitoring):4
