WebP1 : Resuspension buffer (contains RNase A) - RNase will degrade RNA after cell lysis P2: Alkaline (high pH, NaOH) lysis buffer w/ SDS - NaOH lyses the cell, SDS solubilizes lipids and proteins as well as DNA. However,below is a reference where cDNA was eluted from QIAquick PCR Purification Kit columns with potassium phosphate buffer (4 mM, pH 8.5), after replacing the wash buffer (PE) with 5 mMpotassium phosphate(pH 8.5) containing 80% ethanol: Wang HY, Malek RL, Kwitek AE, Greene AS, Luu TV, Behbahani B, Frank B, Quackenbush J, Lee NH. The low concentration of alcohol in the wash buffer eliminates non specific hydrophobic interactions, further enhancing the purity of the bound DNA. RNase A, which is added at the beginning of the procedure, digests the liberated RNA efficiently during the alkaline lysis. The maximum culture volumes recommended forQIAGEN's plasmid preparation kitsstill apply, and should be strictly followed.
