The E.Z.N.A. Blood DNA Maxi Kit is specially designed for large scale isolation of genomic DNA. The kit provides a rapid purification of genomic DNA from up to 20 mL whole blood samples. Sample sources include fresh and frozen whole blood treated with common anticoagulants such as citrate, EDTA and heparin. In addition plasma, serum, buffy coat, bone marrow, lymphocytes, platelets, and body fluid samples can also be used. Phenol/chloroform extractions, and time-consuming steps such as precipitation with isopropanol have been eliminated. DNA purified using the E.Z.N.A. Blood DNA Maxi method is free of contaminants and enzyme inhibitors making it suitable for most downstream applications such as PCR, Southern blotting and restriction enzyme digestion.n of high-quality total DNA
