[Cytometry] Indo-1 on an Aria?

I have an iCyte UV (355) 60mw laser on my Aria and LSR II , they work well for calcium, however the only problem with the aria is the time it takes for the tube to be ejceted, agonist added, then re introduced to the Aria , this can copromise the calcium assay prportional to the kinetics of the agonist

The major problem with doing calcium flux with indo-1 on most Arias is
that indo-1 won't work - at all! - with either a 405 nm or a 375 nm
laser; you'd have to have a 355 (technically, a 325 nm HeCd would work
but I doubt one has ever been mounted in an Aria).
