High Pure PCR Template Preparation Kit
Low to medium throughput genomic DNA isolation.
For general laboratory use.
The High Pure PCR Template Preparation Kit purifies nucleic acids from a wide variety of sample materials, including whole blood, cultured cells, and tissue samples. Bacteria and yeast require a specific pre-lysis treatment with lysozyme or lyticase.
- Minimize DNA loss using a kit that removes contaminants without precipitation or other handling steps that degrade DNA.
- Recover high molecular weight DNA (30 to 50 kb) that is suitable for long-template PCR.
- Improve reliability and reproducibility in downstream applications (real-time, quantitative PCR).
- Save time and maximize flexibility by preparing multiple PCR templates simultaneously.
- Eliminate the use of hazardous organic compounds such as cesium chloride, phenol, chloroform, and ethidium bromide.

Figure 1: PCR amplification of long templates from nucleic acid samples obtained with the High Pure PCR Template Preparation Kit.
Nucleic acids were prepared from blood or cultured human K562 cells. 250 ng of each preparation was amplified using a tissue-plasminogen-activator (tPA)-specific primer and either the Expand Long Template PCR System or the Expand 20 kbPLUS PCR System.
Lane 2 : 6.3 kb; obtained from blood and amplified using Expand Long Template PCR System buffer 1.
Lane 3 : 15 kb; obtained from blood and amplified using Expand Long Template PCR System buffer 3.
Lane 4 : 23 kb; obtained from blood and amplified using Expand Long Template PCR System buffer 3.
Lane 5 : 28 kb; obtained from K562 cells and amplified using Expand 20 kbPLUS PCR System.
Result: All High Pure preparations contained genomic DNA that yielded a distinct band of the expected size.
Figure 2: Southern blot analysis of nucleic acid samples obtained with the High Pure PCR Template Preparation Kit.
Nucleic acids were prepared from cultured mammalian cells (106 K562 cells) and from calf thymus tissue (25 mg). Aliquots of the preparations were digested with Eco RI, purified (see below), separated electrophoretically, and transferred to a membrane by Southern blotting. The blot was hybridized to a DIG-labeled beta-actin antisense RNA probe according to a standard procedure. The hybridized bands (i.e., beta-actin sequences) were detected with an alkaline phosphatase-labeled anti-DIG antibody and visualized via chemiluminescence with CSPD substrate. The blot was exposed to X-ray film for 1 hour.

Lanes 2, 3: 1 µg and 3 µg samples of K562 genomic DNA, purified with the High Pure PCR Product Purification Kit after Eco RI digestion.
Lanes 4-6: 0.3 µg, 1 µg, and 3 µg samples of K562 genomic DNA, purified by conventional phenol/chloroform extraction and ethanol precipitation after Eco RI digestion.
Lanes 7, 8: 0.4 µg and 4 µg samples of calf thymus genomic DNA, purified by conventional phenol/chloroform extraction and ethanol precipitation after Eco RI digestion
Result: All genomic DNA samples isolated using the High Pure PCR Template Preparation Kit were readily and completely cut by Eco RI, were suitable for Southern blot analysis, and contained the expected small and large fragments of the actin gene.
Figure 3: PCR amplification of nucleic acids prepared from paraffin-embedded tissue with the High Pure PCR Template Preparation Kit.
Nucleic acids were purified from formalin-fixed, paraffin-embedded samples of human prostate tissue. An aliquot (10 µL) of each nucleic acid product was used as template for the Expand High Fidelity PCR System (100 µL reaction mixture). The primers were derived from exon 7 of the androgen receptor gene. Aliquots (20 µL) of each amplicon were separated electrophoretically and the gel was stained with ethidium bromide.

Lane 3: Androgen receptor amplicon from half of a full tissue section.
Result: The 263 bp androgen receptor amplicon was clearly visible in both samples.

Note: The lysis buffer contained 10 mg/mL lysozyme for lactobacilli and 1 mg/mL lysozyme for staphylococci together with the amounts of mutanolysin (MU) or lysostaphin (Ly) shown in the first column. The percentages refer to the DNA yield obtained with the highest mutanolysin or lysostaphin concentration and a 30 minute incubation period.
Nucleic acids bind to the surface of the glass fiber fleece in the presence of a chaotropic salt (guanidine HCl). This allows the High Pure filter tube to specifically immobilize nucleic acids (both DNA and RNA) while they are freed of contaminants.
Note: A special Inhibitor Removal Buffer is included which allows the use of heparinized sample material (100 U/mL of heparin). This buffer increases the sensitivity and reproducibility of assays performed with the isolated nucleic acid, even when the sample contains heparin.
Capacity: The High Pure Spin Filter Tubes hold up to 700 μL sample volume.

Blood cells or tissue are lysed by a short incubation with a special Lysis Buffer and Proteinase K in the presence of a chaotropic salt such as guanidine-HCl, which immediately inactivates all nucleases. Cellular nucleic acids bind selectively to special glass fibers pre-packed in the High Pure Purification Filter Tube. Bound nucleic acid is purified in a series of rapid wash-and-spin steps to remove contaminating cellular components. Finally, low salt elution releases the nucleic acid from the glass fiber. This simple method eliminates the need for organic solvent extractions and DNA precipitation, allowing for rapid purification of many samples simultaneously.
DNA is isolated from 25 mg of calf thymus, 1 x 106 K562 cells, and 200 µl of EDTA whole blood. Yield is measured via OD for tissue and cell samples. The quality of the nucleic acid is controlled in an Expand Long Range PCR with a 9.3 kb amplification product for DNA derived from cells. PCR on a LightCycler® Instrument is performed on human blood research samples using kits for Factor V Leiden and CycA.
