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.

Overview

Pierceable adhesive aluminium foil with strong adhesive. Seal is peelable and suitable for high-temperature applications too.

• This aluminium foil seal has a strong acrylic adhesive which produces a seal of high integrity
• It was developed for PCR and other high-temperature applications due to its effectiveness in preventing sample evaporation
• The QuickSeal Foil PCR Seal is pierceable; when pierced, the foil tears in an irregular manner which prevents the formation of a vacuum
• It also has perforated end tabs for easy application and removal by peeling
• For all adhesive seals, the best sealing results are achieved using our Hand Roller or QuickSeal A2000 Auto Sealer

Isothermal nucleic acid Principle Summary

The kit is based on room and constant temperature nucleic acid rapid amplification technology, its principle is that at room and constant temperature, the recombinase and primer form a protein/single-stranded nucleotide complex Rec/ssDNA, and invade the double-stranded DNA template with the help of auxiliary proteins and single-stranded binding protein SSB; then form a D-loop region at the invasion point and start to scan the DNA duplex, after finding the target region complementary to the primer and disintegration of the complex Rec/ssDNA, the polymerase also binds to the 3′ end of the primer to start the chain extension. The kit relies on the role of NFO enzyme and adds the designed specific molecular probes according to the template, and get the result by colloidal gold technology (sandwich method).

K-RHAMNOSE

SKU: 700004334

50 / 100 assays (manual) / 550 assays (microplate) / 550 assays (auto-analyser)

The L-Rhamnose Assay Kit for the measurement of L-rhamnose in plant extracts, culture media/supernatants and other materials is a simple, rapid method.

L-Rhamnose occurs naturally in the L-form and is commonly present as a component of the carbohydrate moiety of eukaryotic glycoproteins and in plant cell wall polysaccharides. The most abundant occurrence of L-rhamnose is within the pectic fraction of plant cell wall polysaccharides. L-Rhamnose is commonly used as a non-metabolisable marker along with lactulose for dual-permeability testing in the diagnosis of intestinal diseases such as Crohn’s disease or coeliac disease.

Note for Content: The number of manual tests per kit can be doubled if all volumes are halved.  This can be readily accommodated using the MegaQuant^TM  Wave Spectrophotometer (D-MQWAVE).

Overview

A transparent, optically clear, DMSO resistant, non-tacky film which adheres only when pressure is applied. It is non-pierceable and peelable. Clear plastic, reflective, glossy on the top. Very thin and light and doesn’t crease easily.

• Crystal clear seal specifically developed for optical applications, particularly qPCR
• Non-sticky when removed from the packaging aiding with handling when using gloves
• When the seal is in position, pressure can be applied to burst the capsules, releasing a strong adhesive only where the seal touches the raised well rims of the plate – the rest of the seal area above the wells remains optically clear
