Hello, I found a potential answer in "Techniques for Work with Plant and Soil Nematodes" pag. 222, using a commercial kit with longer time for DNA extraction (around 4 days). I did not try yet but it seems easy and straightforward.

Hi Valeria,

Thanks for the attachment. I shall have a look at it.

Hi Rolish,

Have you tried the protocol given by Campos and Gilbert (2012)?

Article DNA Extraction from Formalin-Fixed Material

Find below the reference for the publication:

Campos, P.F. and Gilbert, T.M., 2012. DNA extraction from formalin-fixed material. In Ancient DNA (pp. 81-85). Humana Press.

Best,

Mihail
