Equalbit 1 × dsDNA HS (High Sensitivity) Assay Kit is a simple, sensitive and accurate double-stranded DNA (dsDNA) fluorescence quantitative detection kit, which contains pre-mixed working solution (with fluorescent dye) and dsDNA standards. It has good linearity in the range of 0.2 - 100 ng dsDNA, allowing accurate quantification of dsDNA concentrations from 10 pg/μl to 100 ng/μl. In addition, it has good impurity tolerance to common contaminants, such as RNA, salts, free nucleotides, proteins, solvents, detergents, etc. This kit provides a ready-to-use working solution so that operators can directly add samples into it, enabling simple dsDNA sample quantification by the Qubit Fluorometer.
