Quantitate ssDNA and other oligonucleotides accurately and without the need for a highly concentrated sample with Quant-iT OliGreen ssDNA Assay Kit and Quant-iT OliGreen ssDNA Reagent. Quant-iT OliGreen ssDNA Assay Kits contain an ultrasensitive, green-fluorescent nucleic acid stain for quantitating oligonucleotides and single-stranded DNA (ssDNA) in solution. The Quant-iT™ OliGreen™ ssDNA Assay Reagent enables researchers to quantify as little as 1 ng/mL oligonucleotide or ssDNA (200 pg in a 200 μL assay volume) with a fluorescence microplate reader using fluorescein excitation and emission wavelengths. This sensitivity exceeds that achieved with absorbance methods by 10,000-fold.

In addition to the dye, the OliGreen ssDNA Assay Kit includes buffer and an oligonucleotide standard. The OliGreen reagent is also available as the stand-alone Quant-iT OliGreen ssDNA Reagent.
