***Commercial Interest Involved***

Molecular Probes recently introduced SYTO® RNASelect™ green fluorescent
cell stain (S32703). It is more selective toward RNA than any of the
other nucleic acid stains we have previously offered, though will still
give some degree of nuclear labeling. It does however do a nice job of
labeling nucleoi.
