1×dsDNA HS Assay Kit is a rapid, highly sensitive and accurate fluorescent quantitative detection kit for double-stranded DNA (dsDNA). This kit is highly selective for dsDNA and has good linearity in the range of 0.2 ng-100 ng, the quantitation range is between 10 pg/μL to 100 ng/μL. This kit is easy to operate, providing a ready-to-use working solution that enables simple dsDNA sample quantification on Qubit Fluorometer or Fluorescence Microplate Reader. It is ideal choice for NGS large-scale DNA sample quantification (such as input DNA quantification, DNA library quantification, etc.). This kit is well tolerated to common contaminants such as proteins and salts.


  • High sensitive: the concentrations ranging from 10 pg/µ l to 100 ng/µL of dsDNA can be accurately quantified;
  • High specificity: this product is highly selective to dsDNA and is not affected by RNA, has good tolerance to some conventional pollutants, such as salt, free nucleotide, protein, solvent, detergent, etc;
  • Ready to use: 1x working solution, just add the dsDNA sample to be tested and test it with Qubit fluorometer or Fluorescence Microplate Reader at room temperature


  • dsDNA quantification with Qubit or Microplate Reader
  • NGS library quantification
