Stool Sample in Molecular Biology Research:
- Utility and Applications:
- Stool samples are increasingly utilized in animal molecular genetics, population ecology, behavioral ecology, and intestinal disease diagnosis.
- They contain gut microbial DNA, food residue sample DNA, and alimentary tract exfoliated cell DNA.
- Challenges:
- Low content of exfoliated cells in the digestive tract and degradation of genetic material pose primary challenges.
- Presence of inhibitors such as polysaccharides, bile acids, bile salts, bile pigments, digestive juices, and mucus can affect RAP-based molecular analysis.
Importance of DNA Extraction:
Critical Role:
- Selecting appropriate extraction methods is crucial for obtaining high-quality DNA and ensuring successful downstream detection of stool DNA.

Principe
Stool DNA Extraction Process:
- Homogenization and Lysis:
- Stool sample is homogenized and treated in a specially formulated buffer containing detergent.
- This step effectively lyses bacteria, yeast, and fungal samples present in the stool.
- Contaminant Removal:
- Our proprietary Absorber Solution is used to remove humic acid, protéines, polysaccharides, and other contaminants from the lysed sample.
- Binding and Washing:
- Adjusted binding conditions facilitate the attachment of DNA to a DNA Mini Column.
- Two rapid wash steps are performed to remove trace contaminants, ensuring purity of the DNA.
- Elution of Purified DNA:
- Pure DNA is eluted from the column in a low ionic strength buffer.
- The resulting purified DNA is ready for direct use in downstream applications without the need for further purification.
Avantages
