How to determine the concentration and purity of a DNA ,

May 12, 2017 0183 32 Impurities in DNA may lead to inaccurate measurement of DNA concentration and could potentially inhibit subsequent labelling reactions One of the common methods of measuring nucleic acid purity and concentration are spectrophotometric absorbance of a sample at 260nm compared to the value measured at 280nm...

A high throughput DNA extraction method ,

Jul 28, 2012 0183 32 To precipitate the CTAB-DNA complex, the aqueous phase DNA extracts was diluted with 2 volumes of dilution buffer, bringing the NaCl concentration from 12 M extraction buffer down to about 04 M This modification had consistently allowed the precipitation of copious amount of CTAB-DNA complex in a range of plant samples that vary in tissue ....
