	We commonly reuse SYBR Green I,  when traveling with a FluorImager
our sales reps carry a bottle of diluted SYBR Green I as it is the most
"foolproof" DNA stain.  I must confess that I have never used it but many
folks in the lab do on a daily basis and therefore I don't really know
what the stain is diluted in.  Note we are exciting SYBR Green with the
488 nm line from a Argon Laser (I work @ Molecular Dynamics)
happy staining
