AquaGenomicTM is an aqueous reagent for DNA extraction. It may be used to extract DNA from all types of specimens, from bacteria to animal tissues. The extraction protocols are simple, fast, and scalable. AquaGenomic is nontoxic and its lysate may be used for PCR without further DNA purification. Most remarkably, AquaGenomic is highly efficient in extracting DNA from dried specimen swabs. It enables the use of cotton swabs for specimen collection, transportation, and storage at room temperature, therefore, making dried specimen swabs ideal for low-complexity and low-cost biobanking, biosurveillance, and epidemiological research applications.
AquaGenomic is a multi-functional aqueous solution for genomic DNA isolation and purification. It achieves cell lysis, DNA extraction, and debris removal in a single step.
Add AquaGenomic solution to lyse the cells, extract the DNA, and precipitate the cell debris. The crude lysate may be used directly for PCR analysis without further DNA purification.
No columns, no resins, no slurries, no beads, no filters, no membranes, no needles, no cartridges, no manifolds, no multiple solutions and buffers.
No phenol, no chloroform, no isoamylacohol, no saturated butanol, no guanidine hydrochloride.
One AquaGenomic Kit can be used to isolate DNA from cultured cells, buccal swabs, blood, bacteria, animal or plant tissues. No need to purchase different kits for different starting materials.
One single AquaGenomic Kit does all: mini, midi, or maxi. No need to purchase separate mini, midi, or maxi kits.
About 5-10 ug of DNA can be isolated from 1-2 million cultured cells, 15 mg of feces, 1 ml of bacterial cultures, 5-10 mg of animal tissues, or 10-20 mg of plant tissues.
AquaGenomic is priced at $199/kit for 300 minipreps, that is $0.66/miniprep or 1/4 of the price of other genomic DNA isolation kits.
Below is a comparison of AquaGenomic and a leading competitor. You can easily see the advantages and benefits of using AquaGenomic.
Comparison of genomic DNA isolated from different mouse tissues by AquaGenomic. Approximately 10 mg of tissue or 100 ul of blood were processed using the AquaGenomic Kit. Final genomic DNA was suspended in 50 ul deionized water. Five-microliter of each prep was run in a 1% agarose gel.

AquaGenomic Swab Protocol
Cotton swabs are commonly used in forensic evidence collection. However, existing DNA extraction methods can recover only ~100-500 ng of DNA from a dried specimen swab as the majority of DNA remains entrapped within the cotton matrix. With AquaGenomic, ~5-8 ug of DNA can be extracted from a dried specimen swab. It is possible to use cotton swabs for specimen collection, transportation, storage, and DNA extraction for low-complexity and low-cost biobanking, biosurveillance, and epidemiological research applications.
1. Collect the specimen. Use a cotton swab to soak up the specimen (~100-200 ul), such as blood, saliva, mucus, semen, feces, cultured mammalian or bacteria cells, homogenized animal or plant tissues, or any other potential sources of biospecimens. Air-dry the specimen swab at ambient temperature (20-50 °C) for >24 hours. The dried specimen swabs can be shipped at ambient temperature and then stored at room temperature in sealed paper envelopes or plastic bags with desiccant for many years.
2. Extract the proteins and small molecules (dried blood swabs). Cut off the specimen swab tip into a 1.5-ml microfuge tube. Add 400 ul deionized water and soak the swab for >30 min. Use a 1-ml pipet tip to smash the swab ~10 times and press it to the bottom of the tube to squeeze out the solution. Transfer as much liquid as possible (~300 ul) to a new 1.5-ml microfuge tube for analysis of plasma proteins or small molecules.
3. Extract the DNA. Add 300 ul AquaGenomic to the 1.5-ml tube containing the wet swab from Step 2 or a new dried specimen swab. Incubate at 75-85 °C for 30 min. Centrifuge briefly to collect any condensation. Use a 1-ml blue pipet tip to smash the swab ~10 times and press it to the bottom of the tube to squeeze out the solution. Alternatively, homogenize the samples in AquaGenomic in 0.5-ml screw capped tubes with a multichannel bead beater. Transfer as much liquid as possible (~200 ul) to a new 0.5-ml microfuge tube or use a microfuge spin bucket to recover all the lysate from the swab to maximize the DNA yield (Optional: To use the crude lysate for PCR, dilute an aliquot of the crude lysate with 10-20 vol of deionized water and use 0.25 ul of the diluted lysate in a 25-ul PCR reaction).
4. Purify the DNA. Centrifuge at 10,000 xg for 5 min to pellet any debris in the crude lysate. Transfer the clear lysate (~200 ul) to a 0.5-ml tube and mix with 1 vol of isopropanol (~200 ul). Centrifuge at 10,000 xg for 5 min to pellet the DNA. Flip the tube to discard the isopropanol supernatant as completely as possible. Gently shoot 50% isopropanol from a squirt bottle to fill up the tube. Flip the tube to discard the isopropanol rinse as completely as possible. Tap and place the tube upside down on a clean paper towel to remove residual solution. Air-dry the DNA pellet for 5-10 min. Add 100 ul of deionized water to the DNA pellet and let it rehydrate for >15 min. Vortex or pipet up and down to solubilize the DNA. Centrifuge to pellet any insoluble material and transfer the clear DNA solution to a new tube.
