Introduction

With the development of molecular biology, stool, a new non-invasive sample, has been widely used in the research of animal molecular genetics, population ecology, behavioral ecology and some intestinal disease diagnosis. Stool samples includes gut microbial DNA, food residue sample DNA, and alimentary tract exfoliated cell DNA.

The primary problem encountered when using stool sample for molecular biology research is the low content of exfoliated cells in the digestive tract and a certain degree of degradation of genetic material in stool. Another issue in molecular scatology research based on PCR is the presence of a large number of inhibitors in stool that can affect Taq enzyme activity, leading to downstream detection inactivation. These inhibitors include polysaccharides, plant polysaccharides, bile acids, bile salts, bile pigments, digestive juices, mucus, etc. Therefore, selecting appropriate extraction methods to obtain high-quality DNA is the key to successful downstream detection of stool DNA.

At present, the pretreatment methods used in the laboratory, such as phenol/chloroform extraction, cetyltrimethyl bromide (CTAB) lysis, and guanidine isothiocyanate lysis, lack universality in different species, and the success rate of extracting DNA for PCR amplification is also very low. The HiPure Stool DNA Kit provided by Magen Company has opened up a new approach for DNA extraction from stool samples with good universality, high cost-effectiveness, high yield and purification. The reagent kit adopts a unique solution system and inhibitory factor adsorbent, which can efficiently remove various impurities in stool samples. The purified DNA can be directly used for PCR, quantitative PCR and other applications.

This product allows rapid and reliable isolation of high-quality genomic DNA from various stool samples. Up to 100 mg soil samples can be processed in 60 minute. The system combines the reversible nucleic acid binding properties of HiPure matrix with the speed and versatility of spin column technology to eliminate PCR inhibiting compounds such as humic acid from soil samples. Purified DNA is suitable for PCR, restriction digestion, and next-generation sequencing. There are no organic extractions thus reducing plastic waste and hands-on time to allow multiple samples to be processed in parallel.

Principle

Stool sample is homogenized and then treated in a specially formulated buffer containing detergent to lyse bacteria, yeast, and fungal samples. Humic acid, proteins, polysaccharides, and other contaminants are removed using our proprietary Absorber Solution. Binding conditions are then adjusted and the sample is applied to a DNA Mini Column. Two rapid wash steps remove trace contaminants and pure DNA is eluted in low ionic strength buffer. Purified DNA can be directly used in downstream applications without the need for further purification.

Advantages

• High purity – unique adsorbent can completely remove inhibitory factors
• High concentration – maximum extraction of total DNA from stool samples
• High recovery – DNA can be recovered at the level of PG
• Good repeatability – silica technology can obtain ideal results every time

Storage and Stability

Proteinase K and Buffer PCI should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

Principle overview

This kit is based on a room temperature and constant temperature nucleic acid rapid amplification technology: at room temperature and constant temperature, the recombinase and primer form the protein/single-stranded nucleotide complex Rec/ssDNA, with the help of auxiliary proteins and single-stranded binding protein SSB , invade the double-stranded DNA template; form a D-loop region at the invasion site, and start scanning the DNA double-strands; after finding the target region complementary to the primer, the Rec/ssDNA complex disintegrates, and the polymerase also binds to The 3′ end of the primer initiates chain extension. This kit relies on the action of exonuclease at 39 ºC, adding specific molecular probes designed based on the template, and using fluorescence monitoring equipment to achieve real-time monitoring of the amplification process of the target fragment. 

Primer design

It is recommended to use primers with a length of 30-35 bp. Primers that are too short will affect amplification speed and detection sensitivity; primers are designed to avoid the formation of secondary structures that affect amplification; the amplicon length is recommended to be 150-300 bp, usually no more than 500 bp. 

Fluorescent probe design

The probe sequence does not overlap with the specific primer recognition site, is 46-52 nt in length, and the sequence avoids palindromic sequences, internal secondary structures, and continuous repeated bases. The probe has four modification sites: the middle position ≥ 35 nt from the 5′ end is labeled with a dSpacer (tetrahydrofuran, THF) as the recognition site for exonuclease; the upstream of the THF site is labeled with a fluorescent group, and the downstream Label a quenching group, the distance between the two groups is 2-4 nt; THF is ≥15 nt from the 3′ end, and the 3′ end is labeled with a modifying group, such as an amine group, a phosphate group or a C3-Spacer. 

Product features and advantages:

This kit has the advantages of high sensitivity, strong specificity,and short reaction time (only 20 minutes), and the reaction groups are in dry powder state, which is easy to operate and easy to store.

It can be applied to various brands of fluorescence quantitative PCR instruments, constant temperature fluorescence amplification instruments and other fluorescence detection equipment.
