Genomic DNA Purification Kit
MasterPure™ Complete DNA and RNA Purification Kit
- Purification of TNA, DNA, or RNA for many applications, including PCR, RT-PCR, cloning, sequencing, Northern and Southern blotting, restriction analysis, and genomic library preparation.
The MasterPure™ Complete DNA and RNA Purification Kit uses a novel technology that enables efficient purification of intact total nucleic acid (TNA), DNA, or RNA from every type of biological material (Table 1 and Fig. 1).
The gentle salt-precipitation protocol permits rapid purification of high-molecular-weight nucleic acids from a single sample or many samples that are processed simultaneously (Fig. 4). High yields of nucleic acids are obtained using MasterPure Kits (Table 2), and yields and purity are highly consistent for different samples of the same material (Fig. 2). The resultant nucleic acids have an A260/A280 ratio of 1.8-2.0, indicating that they are substantially free of protein. The TNA, DNA, and/or RNA purified from different samples can be used directly in many applications. For example, the sensitivity of PCR or RT-PCR assays is often improved if the template is obtained using a MasterPure Purification Kit.
- Purify TNA in 30 minutes without cumbersome columns.
- A260/A280 ratios consistently between 1.8 and 2.0.
- Recover >90% of theoretical DNA yield.
- No phenol, chloroform, or other caustic solvents.
- Each kit component is also available separately in a 10X package size.
- Low- and high-molecular-weight nucleic acids are recovered.

MasterPure™ Plant Leaf DNA Purification Kit
- Purification of plant-leaf DNA for microsatellite typing, PCR amplification, restriction digestion, Southern blotting, and other molecular biology applications.
The MasterPure™ Plant Leaf DNA Purification Kit is designed for purifying DNA from 35-100 mg of fresh plant-leaf tissue. The protocol can be completed in less than 1 hour and may be scaled up to obtain larger amounts of DNA. The purified DNA can be used for PCR amplification, restriction digestion, Southern blotting, or other molecular biology applications.
The MasterPure Kit was designed for even the most difficult plant leaf DNA purifications. The kit was optimized with the grapevine, Vitis vinifera, whose leaves are notoriously high in polyphenolic (tannin-like) compounds and polysaccharides, which can interfere with both the isolation and subsequent use of DNA. Plants tested include grape, apple, tomato, maize, sugarcane, sunflower, fern, quillwort, and pine.
- Recover DNA from the leaves of many plant species, even those high in polysaccharides and polyphenolic compounds.
- Purify DNA in less than 1 hour.
- Yields high-molecular-weight DNA (Fig. 1).
- No organic solvent or CTAB extractions, CsCl gradients, or enzyme digestions.
- Recover DNA of higher integrity than column-based purification methods (Fig. 2).

Meta-G-Nome™ DNA Isolation Kit
- Isolation of fosmid cloning-ready metagenomic DNA from microbes in water, soil, and compost samples.
- Isolation of metagenomic DNA for PCR or next-generation sequencing.
Note: The Meta-G-Nome™ DNA Isolation Kit replaces Epicentre's Metagenomic DNA Isolation Kit for Water.
The Meta-G-Nome™ DNA Isolation Kit is used to isolate inhibitor-free, fosmid cloning-ready DNA from unculturable or difficult-to-culture microbial species present in environmental water, soil, or compost samples (Fig. 1). The kit isolates high-molecular-weight DNA that is randomly sheared (with fragment sizes approximately 40 kb), does not require size selection, and can be used directly for end-repair and construction of fosmid libraries, PCR amplification, or next-generation sequencing. The kit can also be used to prepare 16S rRNA metagenomic libraries for phylogenetic classification or species-abundance studies.
The procedure uses filtration technology (with 1.2-µm and 0.45-µm membranes provided) and enzymatic lysis (with Ready-Lyse™ Lysozyme and Proteinase K) to isolate metagenomic DNA from water (100 ml per extraction), soil (1 g per extraction), or compost (300 mg per extraction). The purified DNA is free from humic and fulvic acids.
- No bead-beating, agarose plugs, pulsed-field gel electrophoresis, or size selection.
- No phenol/chloroform extractions or CTAB.

- Easy isolation of fosmid cloning-ready metagenomic DNA from microbes, including Gram-positive bacteria, in a water sample.
- Isolation of metagenomic DNA for PCR or next-gen sequencing.
The Metagenomic DNA Isolation Kit for Water was developed to isolate metagenomic DNA directly from culturable or unculturable microbes in a water sample, to generate cloning-ready DNA for construction of random-sheared fosmid libraries. Traditional methods for isolation of metagenomic DNA to be used in fosmid library construction involve agarose plugs, random shearing, and a size selection using pulse-field gel electrophoresis before cloning into a fosmid vector. These methods (Fig. 1B) are time-consuming, inefficient, and result in a library with biased genome representation. The Metagenomic DNA Isolation Kit for Water isolates high-molecular-weight DNA that is randomly sheared (with fragment sizes approximately 40 kb), does not require size selection (Fig. 1A), and can be used directly for end-repair and cloning into the Epicentre pCC1FOS™ Vector (CopyControl™ Fosmid Library Production Kit, sold separately).
The kit protocol uses Ready-Lyse™ Lysozyme followed by Proteinase K treatment to isolate high-molecular-weight DNA. Using this kit, DNA isolated from 300 ml of lake water can result in a fosmid library containing as many as 100,000 metagenomic clones.
- No bead-beating.
- No agarose plugs, mechanical shearing, or size selection.
- Prevents loss of DNA, thereby generating unbiased libraries.
- No columns or phenol/chloroform extractions.
- Fosmid cloning-ready DNA (Fig. 2) in 90 minutes.
- Improved yield, increasing the probability of recovering DNA from low-abundant organisms present in the collective genomes in environmental samples.
