Promega Corporation has introduced the QuantiFluor ssDNA
system for highly sensitive quantitation of single-stranded DNA (ssDNA). The
QuantiFluor ssDNA dye enables quantitation of small amounts (as little as 200
pg per well) of ssDNA in solution, saving sample for downstream assays.
For low-concentration samples, the system delivers sensitivity
greater than absorbance at 260 nm, and has a higher dynamic range.
The system includes the required reagents to deliver
consistent ssDNA quantitation results. It is easy to set up on microplate or
single-tube fluorometers, and is available as an integrated solution with
