Nonaqueous catalytic fluorometric trace determination of vanadium based on the pyronine B-hydrogen peroxide reaction and flow injection after cloud point extraction.

E K Paleologos et al.

Analytical chemistry, 73(18), 4428-4433 (2001-09-29)

The catalytic effect of vanadium on the pyronine B-H2O2 system is examined. Enhancement of the catalytic reaction rate along with the efficiency and selectivity against vanadium is achieved in a formic acid environment in the presence of a nonionic surfactant

Nucleic acid dyes for detection of apoptosis in live cells.

T Frey

Cytometry, 21(3), 265-274 (1995-11-01)

Apoptotic thymocytes were found to be much dimmer than normal thymocytes when stained with several nucleic acid dyes. These dyes provide a quick and simple assay for apoptosis which works for live cells and does not require a UV laser.
