MagMAX™ DNA Multi-Sample Kit (Invitrogen™)

MagMAX™ DNA Multi-Sample Kits are designed for rapid purification of high-quality genomic DNA from a variety of sample types including blood and blood cards, tissue, mouse tails, buccal swabs, buffy coats, and cultured cells. These purification kits use MagMAX™ magnetic bead-based nucleic acid isolation technology to produce high yields of purified DNA, free from inhibitors that may affect downstream reactions such as genotyping assays, CE and next-generation sequencing, and high resolution melting analysis. The 50 prep kit is designed for manual microfuge tube processing.

The demands for DNA yield and purity have become more stringent with the development of new analytical methods and technologies, such as high-throughput genotyping, and next-generation DNA sequencing platforms. MagMAX™ DNA Multi-Sample Kits meet the challenge by delivering highly pure DNA that is free of nucleases, proteins, and other inhibitors of downstream enzymatic reactions.
As shown in Table 1, DNA with high yield and purity can be obtained from a variety of materials using the MagMAX™ DNA Multi-Sample Kits. This is in contrast to filter membrane–based methods that often require different kit configurations for various input materials. For applications requiring maximal yields, for small batch sizes, or for DNA archival purposes MagMAX™ DNA Multi-Sample Kit (tube format, manual processing) may be desirable because larger sample inputs are accommodated. DNA yields suitable for most routine applications may be obtained using the MagMAX™-96 DNA Multi-Sample Kits (96-well plate format, compatible with automated handling) (Table 1).

The MagMAX™ DNA Multi-Sample Kit also delivers high yields of DNA from lipid or glycogen rich samples, such as brain and liver tissues, respectively. Figure 1 shows more than twice as much DNA was purified from tissues with the MagMAX™ DNA Multi-Sample Kit than with the leading competitor’s filter membrane–based method.

Most enzymatic molecular applications are prone to inhibition by analytes carried over from the sample matrix (e.g., heme, heparin, salts, protein) or the purification method itself (phenol, salts, alcohol). Figure 2 illustrates the effect of DNA purity on sensitive molecular applications, such as quantitative PCR (qPCR). DNA was extracted from blood using the MagMAX™-96 DNA Multi-Sample Kit, or a competitor’s filter membrane–based kit and subjected to real-time PCR analysis. The cycle threshold CT values obtained with the DNA purified using the MagMAX™ DNA Multi-Sample Kit were lower than those obtained with the filter membrane kit–purified DNA, indicating the MagMAX™ kit yields higher-purity DNA.

MagMAX™ DNA Multi-Sample Kits provide purified DNA that is suitable for a variety of Applied Biosystems application workflows (Figure 3), including SNP genotyping and DNA sequencing analysis (see Figure 4).
