The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. There are two main effects of removing divalent cations with EDTA: (1) destabilization of bacterial lipid membranes and (2) inhibition of DNases, which often require divalent cations as cofactors. Where is your DNA? This handling error leads to inefficient cell lysis, and incomplete precipitation of SDS, cell debris, and genomic DNA. To overcome this, continue mixing the solution by inverting it gentlyuntil a homogeneous blue suspension is achieved. RNase A, which is added at the beginning of the procedure, digests the liberated RNA efficiently during the alkaline lysis. Most of the recent formulations do not contain lysozyme and glucose. Glucose is added to make the solution isotonic.
