I will try tissue protocol then. Another question, I was reading some papers and they recommend pH 6 – 7 for silica DNA adsortion, could you explain why your pH lysis buffer is 7,6 – 8?
I was reading your protocol of gDNA extraction with beads and a got confused with ratio mentioned 2:3:4. How is it used with blood sample and without TE buffer at beggining? It’s 140ul of blood and 20ul magnetic bead?
