Pentaammonium Salt Purity: 90% Designed to operate at longer wavelengths of excitation, this chelator responds to Ca2+ without significant changes in excitation or emission maxima. There are several advantages that this offers such as using other fluorescent probes simultaneously, the suitabiligy of argon laser sources for excitations, and less interference from endogerous autofluorescence. This is the newest member of the chelator family. |
