Plant DNAzol™ Reagent is a ready-to-use organic reagent formulated for the isolation of high quality genomic DNA from a variety of plant samples.

• Permits use on broad spectrum plant material
• Rapid isolation of genomic DNA

RNA Hydrolysis for Efficient Isolation of Genomic DNA from a Variety of Sample Sources
Plant DNAzol™ Reagent can be used for the efficient isolation of genomic DNA from a variety of plant tissues such as leaf, seed stem, root, and callus. The Plant DNAzol™ procedure is based on the use of a novel guanidine-detergent lysing solution that hydrolyzes RNA and allows the selective precipitation of DNA from the lysate.

Isolate Genomic Plant DNA in About an Hour
In the Plant DNAzol™ procedure, plant samples are pulverized in liquid nitrogen or homogenized, and genomic DNA is extracted from the homogenate with the Plant DNAzol™ Reagent. Following extraction, plant debris is removed by centrifugation and DNA is precipitated from the supernatant with ethanol, and solubilized with TE buffer (pH 8.0). The entire procedure can be completed in approximately 60-70 minutes.

Comparable Yield in Less Time and with Fewer Reagents
Unlike traditional methods for plant DNA extraction (e.g., CTAB), Plant DNAzol™ is quicker, does not require RNase A to remove RNA from genomic DNA preparations, and in the majority of tissues, does not require phenol. Furthermore, use of Plant DNAzol™ generates yields from plant tissue that are comparable with the traditional CTAB method.

Frequently asked questions (FAQs)

Will DNAzol Reagent isolate only genomic DNA or will plasmid DNA also be isolated? How about mitochondrial DNA?

The DNA isolated is actually total DNA, so plasmid DNA will be isolated along with genomic DNA. The mitochondrial genome is similar to a plasmid and can be isolated using DNAzol Reagent. The 1 minute room temperature incubation in ethanol before centrifugation should be extended to 5-10 minutes for maximum recovery.

At what temperatures can DNAzol reagent be stored and still be okay to use? Are there possible stopping/storage points in the protocol?

We recommend storing DNAzol Reagent at room temperature. The DNAzol lysate (homogenate) can be stored 1 month at 15-30 degrees C; after 10 months at 4 degrees C or -20 degrees C, the DNAzol lysate (homogenate) has yielded high molecular weight genomic DNA, which can be completely digested with restriction enzymes and works well in PCR. During washes, DNA can be stored in 95% EtOH for at least one week at 15 degrees C to 30 degrees C or for three months at approximately 4 degrees C. DNA can be stored in DNAzol Reagent for one month at room temperature or 10 months at 4 degrees C.

I'm interested in isolating plant DNA, but am worried about the abundance of carbohydrates and complex polysaccharides in the tissue. What kit do you recommend for this?

We offer several kits specifically designed to isolate plant DNA depending on the amount of starting material and chemistry you are interested in using. Please use this link for a comparison of our kits available for plant DNA extraction.

After DNAzol reagent extraction, my OD 260/280 ratio is low. Does this mean I have poor-quality DNA?

Consider the following if you have a low 260/280 ratio:

The correct amount of DNAzol reagent may not have been used. If DNAzol reagent was added to a cell pellet, make sure that the volume of reagent is 20 times that of the cell pellet.

There may have been a problem in pipetting away the viscous supernatant from the DNA pellet, leading to contamination with protein. The DNA may be used with DNAzol reagent again or extracted with phenol to remove the protein.

In some samples dissolved in water, the ratio may be low due to the acidity of the water or the low ion content in the water. The ratios may go up if the sample is dissolved in TE and the spec is zeroed with TE (or 1 to 3 mM Na2PO4, pH ~8.0). [See BioTechniques 22:474-6, 478-81 (1997).]. The molar extinction coefficient of the nucleotides is given at neutral pH, suggesting that the absorbance at 260 nm would be highest at neutral pH. Of course, DNA is not stable under acidic conditions so degradation may occur if the DNA is left in this condition for too long.
