Fluo-4 Pentapotassium Salt 494nm 500ug , Each

Details:

Fluo-4 pentapotassium salt 500ug^ fluo-4 has its absorption maximum at 494 nm, thus making it excitable by the argon-ion laser. Fluo-4 is essentially nonfluorescent without ca2 present, but the fluorescence increases at least 100 times on ca2 binding. S
