9-(2-Carboxyphenyl)-2,7-dichloro-4,5-bis[di(2-pyridyl)aminomethyl]-6-hydroxy-3-xanthanone ZINPYR-1

Technical Note:
1. ZINPYR-1 is a new lipophilic, zinc-sensitive, fluorescent dye able to penetrate cell membranes. E xcitation and emission
wavelengths are in the visible range (lambda> 500nm). This property is a clear advantage over other dyes requiring high energy, tissue damaging UV radiation.
