I am using 1% CTAB for extracellular DNA extraction, followed by isopropanol precipitation, phenol chloroform extraction, ethanol precipitation and wash. How can I increase my yield?
Normally when we work with small biomass of samples (knowing the yield will be low), we tend to allow the DNA to precipitate overnight at 4'C after adding isopropanol.
we use anion exchange chromatography to obtain high yields of free-floating extracellular DNA from different water sources. Check our pre-printed below. Hope it helps.
