How can we improve 260/230 ratio after DNA extraction from macroalgae?

19 April 2023 0 1K Report

Hi,

We have extracted DNA from macroalgae samples with different kits and a CTAB protocol, but in every trial we obtained a low 260/230 ratio (the best has been 0.70). Does anyone know how to improve it? Or does anyone know any procedure to process macroalgae samples for DNA extraction with good 260/230 ratios?

Many thanks,

Filippo
