Hello to all,

     I have a user who would like to look at Ca+2 levels.  I have never run
     this before and would like to know what others think is the best
     reagent for this measurement.  We have a UV laser (Coherent Innova
     300) on our MoFlo so we can run Indo1.  In my reading, Indo1 seems
     like the dye of choice since using the ratio of the 2 emissions for
     bound and unbound Ca+2 eliminates problems with loading differences
     and size differences of a population of cells.  What do you
     experienced cytometrists think?  Thanks for your input.
