It was several years ago when I bought indo1-AM from sigma. The reason was, as I can remember, that is was cheaper compared to molecular probes. This material was also orange and did not stain the cells at all. I believe the vial contained just indo1 not the methyl-ester. May be there were some problems with storage during shipping. From then on I turned to Molecular Probes with no further complaints as I can remember. Attila
