The PureLink® Genomic DNA Mini Kit and PureLink® 96 Genomic DNA Kit enable high-yield, high-purity DNA extractions from a wide variety of sample types, including blood, tissues, cells, bacteria, swabs, and blood spots, in a familiar silica spin-column or semi-skirted 96-well plate format. Using the PureLink® Genomic DNA Kits, you will:
Obtain higher gDNA yields and purity - optimized spin-column membrane and buffer formulations
Save time and money - use with a large range of sample sizes (e.g., 100 µl to 1 ml blood); 96-well version does not require special equipment
Increase flexibility - one kit works with a variety of sample types

How it works
The PureLink® Genomic DNA Mini Kit protocol improves upon the easy, familiar spin-column methods currently in use (Figures 1 and 2). Columns are newly configured to bind and release DNA more efficiently. Samples are lysed in an optimized buffer formulated to enhance proteinase K activity and eliminate protein contamination. The chaotropic salt binding buffer allows the highest DNA binding of any column method. Powerful wash buffers remove all traces of protein and salt. DNA is eluted in a low-salt buffer to allow for pH stabilization of the DNA in storage.

For higher throughput, use the PureLink® 96 Genomic DNA Kit (Figure 3). In this 96-well version, sample processing is performed with either a vacuum manifold or centrifugation at only 2,250 g, allowing you more flexibility in centrifuge choice. The semi-skirted plate design is compatible with most vacuum manifolds on robotic workstations.

Higher yields and purity
With the PureLink® Genomic DNA Kits, youll get greater yields of higher-purity gDNA (determined by A260/A280 measurements) with all of your sample types - from bacteria to tissues to blood to cells (Figures 4-6). The PureLink® 96 Genomic DNA Kit outperforms competitor products in both DNA yield and purity for multiple sample types, including blood (Figure 7). A260/A280 and A260/A230 ratios of PureLink® gDNA are higher than those obtained with other kits, indicating no contamination carryover of protein or guanidine using the enhanced PureLink® Lysis and Wash Buffers (Figure 7).

Overview
It is necessary to remove excess primers and unincorporated nucleotides from the PCR reaction prior to sequencing.

An enzymatic cleanup method offers precision and speed over technologies such as spin columns or beads. ExoSAP-IT Express reagent consists of two hydrolytic enzymes, a modified Exonuclease I and Shrimp Alkaline Phosphatase (SAP), in a specially formulated buffer. It is used to remove excess primers and dNTPs from a PCR mixture with no interference in downstream applications. This unique, highly stable, one tube solution allows for greater confidence and superior sequencing results (Fig. 1).

Innovative solution
Our scientists engineered Exonuclease I to have increased heat lability, allowing for inactivation in only 1 minute (Fig. 2). ExoSAP-IT Express reagent is added directly to the PCR product for a 4 minute cleanup at 37°C, followed by a 1 minute inactivation at 80°C, which provides accurate and consistent results in just 5 minutes.

Fastest PCR cleanup method
This novel technology allows for a significant reduction in sample cleanup time with minimal steps, providing the simplest workflow (Fig. 3). ExoSAP-IT Express reagent offers rapid turnaround times and improved efficiency of resources while delivering the quality that scientists have become accustomed to when using ExoSAP-IT for PCR product cleanup.

Conserve PCR samples — simple one step, 100% recovery
The ExoSAP-IT Express enzymatic cleanup method is designed to minimize errors by reducing your protocol to a single pipette step, allowing for automated or manual processing from a single tube or microtiter well. ExoSAP-IT Express reagent outperforms the competition by ensuring 100% recovery of all amplicon sizes, both short and long (Table 1).

ExoSAP-IT Express PCR Product Cleanup is active in commonly used PCR buffers, so no buffer exchange is required. After treatment, ExoSAP-IT Express reagent is inactivated by heating at 80°C for 1 minute. The treated PCR products are then ready for subsequent analysis in applications that require DNA to be free of excess primers and nucleotides.

The MagMAX Cell-Free Total Nucleic Acid Isolation Kit is designed for enrichment of all nucleic acid species present in cell-free biological samples such as plasma. The kit utilizes MagMAX magnetic-bead technology, ensuring reproducible recovery of high-quality nucleic acid that is suitable for a broad range of applications, including real-time PCR, digital PCR, and next-generation sequencing.

The magnetic bead–based purification format allows you to easily process a wide range of sample input volumes (1 mL to 6 mL). When used with the KingFisher Duo Prime or KingFisher Flex Magnetic Particle Processor, 6 to 24 plasma samples of 2-mL input volume can be isolated at once. Alternatively, samples can be processed manually with the use of a magnetic stand.

Features of the MagMAX Cell-Free Total Nucleic Acid Isolation Kit include:
• Automation-ready, phenol-free extraction
• Fast procedure allows 6 to 24 samples to be processed in 90 minutes or less when used with the KingFisher Duo Prime or KingFisher Flex Magnetic Particle Processor with a 24 Deep Well Head

Go beyond cell-free DNA and get the total picture
Isolating and analyzing circulating cell-free total nucleic acid (cfTNA) from plasma and other cell-free samples serves as a non-invasive method to detect and monitor targets associated with certain disease states such as cancer.

The first step in attaining this valuable information is efficient nucleic acid isolation that specifically recovers the circulating nucleic acid species that contains information related to the disease state. The importance of cell-free DNA (cfDNA) is becoming established, but it may not tell the whole story. Cell-free RNA (cfRNA) sequences serve as critical biomarkers as well in the form of microRNAs and gene fusions. This inclusion of the cfRNA with the cfDNA provides an opportunity for researchers to expand their studies and advance human health.

The MagMAX Cell-Free Total Nucleic Acid kit is developed by the same Thermo Fisher Scientific scientists that brought you the MagMAX Cell-Free DNA Isolation Kit. The difference is the inclusion of all cfRNA species in the eluate, allowing you to increase the amount of information available from a single cell-free sample. Just like the cfDNA Isolation Kit, the cfTNA kit is designed for both manual and automated isolation of nucleic acid from a wide sample volume input range of 1 to 6 mL. The phenol-free, magnetic-bead format makes the kit fully amenable to automated isolation.

Thanks to the scalable format that allows for various sample inputs, it is possible to vary the number of samples processed with a single kit. For example, enough reagents are provided to process 50 samples of 2 mL plasma each. Alternatively, with the same kit it is possible to process 25 samples of 4 mL plasma each. Higher and lower input volumes are possible and the number of samples that can be processed will vary accordingly. This unique product attribute allows you to tailor the product to your specific needs.

Benefits of MagMAX magnetic bead–based purification
Magnetic beads offer many benefits compared to other technologies for isolating nucleic acid. Beads bind the DNA more efficiently than glass-fiber filters, resulting in higher and more consistent yields. Additionally, because filters and vacuum manifolds are not used, there is no risk of filter clogging due to cellular particulates in samples. This clogging issue is of particular concern with protein-rich, large-volume samples such as plasma that are commonly used in circulating cell-free nucleic acid studies.

• Removal of linkers following ligation
• Removal of residual salts, phenol, chloroform, or ethidium bromide
• Purification of RNA-free plasmid DNA

Includes Silica Powder Suspension Binding Buffer Concentrated Washing Buffer TBE Conversion Buffer Detailed ProtocolNote

Care should be taken to avoid DNA damage with UV light when the gel-purified DNA fragment will be used in downstream cloning reactions. Always use a long wavelength UV (360 nm) light-box during excision of the gel slice. If only a short-wavelength UV (254 to 312 nm) light-box is available, minimize the UV exposure to a few seconds or keep the gel on a glass or plastic plate. Alternatively, visible dyes can be included in standard agarose gels to allow for visualization of the DNA bands in ambient light (2, 3).

MagMAX™ DNA Multi-Sample 96-Well 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 96-prep and 5x 96-prep kits are designed for higher throughput and automated format 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). To see the full performance description of DNA purified using the MagMAX™ DNA Multi-Sample Kits in TaqMan® SNP genotyping assays and with BigDye® chemistry in DNA sequence analysis, view the MagMAX™ DNA Multi-Sample Kit Product Bulletin.
