Merck, DNAQF-1KT, DNA Quantitation Kit, Fluorescence Assay

General description
The kit has all the reagents necessary for quantitation of DNA using the fluorescent dye bisBenzimide (Hoechst 33258). The kit allows highly sensitive, quick, and accurate determinations of double-stranded DNA from 10ng/ml to 5μg/ml, even in the presence of RNA and proteins. Fluorometry is a highly sensitive and simple method used for DNA quantitation. The fluorescent dye, bisBenzimide H 33258, which binds primarily to AT sequences in the minor groove of double-stranded DNA (dsDNA), is specific for quantitation of nanogram amounts of DNA (10 ng/ml to 10 mg/ml). When excited at 360 nm, the fluorescence emission at 460 nm of the dye increases significantly in the presence of DNA.
Application
DNA Quantitation Kit, Fluorescence Assay has been used to measure the concentration/content of DNA:
in neonatal rat ventricular myocytes (NRVMs)
in human mesenchymal stem cells (hMSCs)/samples for normalization of the relative alkaline phosphatase (ALP) amount
in mouse embryonic fibroblast cell line (NIH3T3 cells)

Features and Benefits
Specific for the quantitation of nanogram amounts of DNA
Works well with purified preparations as well as with DNA from crude extracts containing RNA and proteins
