After the clear pellet appears, add 500L of TE buffer or elution buffer to the pellet and dissolve the DNA in it. DNA extractions using the NGS protocol with (D) no PVP, (E) 1% PVP, and (F) 4% PVP. CTAB serves as an important surfactant in the DNA extraction buffer system to remove membrane lipids and promote cell lysis. The DNA is insoluble in the alcohol and will come out of solution, and the alcohol serves as a wash to remove the salt previously added. Nonpolar molecules migrate into the organic phase and leave behind DNA and other polar molecules in the aqueous phase. After a considerable amount of time, the DNA may eventually float to the top of the alcohol layer. Fast ID is able to extract DNA from a wide variety of sample types. In this case, after adding TE and NaCl to cell pellet, add lysozyme to 1 mg/ml, and incubate 1 hour at 37C. After grinding, the tissue is transferred to a tube and CTAB buffer is added.
