从血液中纯化基因组DNA、线粒体DNA或病毒DNA，最高可达600 μg
QIAamp DNA Blood Maxi Kit应用硅胶模技术，用于实验室从全血、血浆、血清和其它体液中纯化DNA。QIAamp DNA Blood Maxi Kit可处理3–10 ml新鲜或冷冻的人类全血。QIAamp Maxi离心柱可在离心机或真空装置上处理（使用真空装置需要额外的缓冲液AW1 [货号：19081]和AW2 [货号：19072] ）。
Optimized buffers lyse samples, stabilize nucleic acids, and enhance selective DNA adsorption to the QIAamp membrane. Alcohol is added and lysates loaded onto the QIAamp spin column. Wash buffers are used to remove impurities and pure, ready-to-use DNA is then eluted in water or low-salt buffer. |Genomic DNA from 8 blood samples stored at 4°C for 1 week. DNA was purified using the QIAamp DNA Blood Mini Kit. When blood is stored at 4°C, the DNA is rapidly degraded due to apoptosis; the resulting apoptotic banding pattern can clearly be seen in these samples. M1: lambda-HindIII; M2:100 bp ladder.|Amplification of a 10 kb fragment of the human ALDH1 gene from genomic DNA isolated from blood. DNA was purified using conventional methods (Phenol) or the QIAamp DNA Blood Maxi Kit (QIAamp). PCR products were sequenced directly. M: 1 kb ladder.|Three paternity cases tested with DNA purified from blood samples with the QIAamp DNA Blood Mini Kit. 1: mother; 2: child; 3: alleged father; 4: child + alleged father. M: markers. Each lane had 3 µg of DNA loaded. Outcome: A: alleged father excluded; B & C: alleged father confirmed. (Data kindly provided by J. James, Gene Proof Technologies, Nashville, TN, USA.)|
QIAamp DNA Blood Kits根据样本存储条件和新鲜程度不同，可纯化获得200 bp–50 kb的DNA（参见"Apoptotic banding in stored blood"）。纯化的DNA适用于长片段PCR扩增（参见"Long-range PCR"）和RFLP分析等等，如亲子鉴定（参见"Paternity testing by RFLP analysis"）。
使用QIAamp DNA Blood Maxi Kit获得DNA的回收率可高达95.8%，依初始细胞密度而定（见表）。
无需苯酚-氯仿抽提。DNA特异性结合到QIAamp硅胶膜上，让污染物流过。PCR抑制物，如：二价阳离子和蛋白，可通过两步有效的洗涤步骤被完全去除，结合在离心柱上的纯核酸可用水或试剂盒中的缓冲液洗脱。
QIAamp DNA Blood Maxi Kit采用快速离心柱操作简化了从全血或相关体液中纯化DNA的流程（参见"procedure"）。该试剂盒可处理带有EDTA、柠檬酸盐和肝素等常规抗凝剂的新鲜或冷冻的全血样本。QIAamp DNA Blood Maxi Kit可处理3–10 ml的样本，制备时间55分钟。可从10 ml健康全血中获得300–600 µg DNA，洗脱体积500–2000 µl。
QIAamp DNA Blood Kits提供全面的操作手册，包括从不同来源的样本中纯化DNA的操作流程。QIAamp样本制备技术已完全经过验证。
QIAamp DNA Blood Maxi Kit使用经验证的QIAamp技术，采用带有50 ml收集管的Maxi离心柱从不同来源的样本中纯化DNA。样本来源包括：
