Highly sensitive, easy to use, fluorescent dye for ssDNA Quantitation

QuantiFluor® ssDNA System


The QuantiFluor® ssDNA System contains a fluorescent dye that enables sensitive quantitation of small amounts of single-stranded (ssDNA) in solution. Detecting and quantitating ssDNA is useful for a variety of molecular biology research applications. These include studying ssDNA viruses, quantitating short synthetic ssDNA probes for site-directed mutagenesis, analysis of first-strand cDNAs, and quantitating bisulfate-treated DNA to study DNA methylation.


For low-concentration samples, sensitivity of the QuantiFluor® ssDNA System is significantly increased (several thousand-fold) compared to absorbance at 260nm (NanoDrop® method).


The QuantiFluor® ssDNA System requires less DNA (200pg) than other methods (~1 µg). You save more of your precious sample for downstream assays.


System includes all the necessary reagents to quickly set up and quantitate ssDNA.

Offers an integrated solution with instrument pairing. Sets up easily on microplate or single-tube fluorometers from Promega.
