ProtocolSDS
Application
- For quantitative determination of DNA.
Key Features
- Sensitive and accurate. Linear detection range 2 ng to 40 ng (100 - 2,000 ng/mL) calf thymus DNA in 96-well plate assay.

More Details
- DNA quantitation is a common practice in molecular biology. Very often DNA is available in minute quantities and the traditional UV 260 nm absorbance method requires microgram quantities for reliable results. Accurate determination of DNA concentration, especially when DNA is present at low concentrations, is crucial for reproducible results in sequencing, cloning, transfection and DNA labeling. Simple, direct and automation-ready procedures for measuring DNA concentration are very desirable. BioAssay Systems QuantiFluo™ DNA assay kit is designed to accurately measure nanogram quantities of plasmid DNA, cDNA, DNA following polymerase chain reaction and DNA eluted from gels. The improved method utilizes Hoechst dye that binds specifically with double-stranded DNA. The fluorescence intensity, measured at λex/em = 350/450nm, is directly proportional to the DNA concentration in the sample. The optimized formulation substantially reduces interference by substances in the raw samples.
Can you guarrantee, that your kit enables an accurate estimation of cDNA concentration in RT reaction mixture, where high excess of total RNA is present? Is it a SYBR Green based method?
We are using Hoechst dye based DNA assay. It is very specific for DNA and not RNA. However, as we do not know the RNA content in your sample, we can not judge if it would meet your needs.For more detailed product information and questions, please feel free to Contact Us.
