The TIANamp Blood DNA Kit uses spin columns which can specifically bind to DNA, and provides unique buffer system for effective blood gDNA extraction. The spin column is made of new type silica membrane which can bind DNA efficiently and specifically. It can maximally remove contaminant proteins and other organic compounds in cells. Genomic DNA isolated by the kit is stable with good integrity and purity. - Wide application: The kit could be used to extract gDNA from anticoagulant blood (EDTA, heparin, etc.), buffy coat and blood clots directly. - High quality: With the unique lysis buffer system, the purified DNA with high concentration, purity and good integrity could satisfy the demands of chip hybridization and high-throughput sequencing. - Rapid and non-toxic: The kit uses silica membrane adsorption technology and does not need phenol and chloroform. The whole extraction process could be completed within 1 hour.
