Introduction

This Kit is designed to purify genomic DNA and total RNA simultaneously from a single biological sample. Lysate is first passed through a DNA spin column to selectively isolate DNA and then through an RNA column to selectively isolate RNA. Pure DNA and RNA are purified from the entire sample, in contrast to other procedures where either the biological sample or the purified total nucleic acids is divided into two before being processed separately. The kit is compatible with small amounts of a wide range of animal cells and tissues.

Specifications

Features	Specifications
Main Functions	Co-isolation DNA and RNA from skin, muscle, connective tissue, fibrous tissue sample
Applications	PCR and southern blot, etc.
Purification method	Mini spin column
Purification technology	Silica technology
Process method	Manual (centrifugation or vacuum)
Sample type	Cultured cells and tissue samples
Sample amount	Tissue: < 20mg

Principle

The Kits are designed to purify both genomic DNA and total RNA from the same cellor tissue sample. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column and bind DNA. Ethanol is added to the flow-through and the sample is applied to an RNA column. DNA/RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 30µl water using the Kit. High-quality DNA is eluted in as little as 50µl water using the Kit.

Advantages

• High quality – high purity total RNA / DNA can be directly used in a variety of downstream applications
• Fast – column method can complete the extraction of several samples in 30 minutes
• Safe – no phenol chloroform extraction required
• Simultaneous extraction- simultaneously isolate DNA and RNA from one sample

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.
