หลักการ

• Principle of HiPure Silica Gel Column: Utilizes a high binding ability glass fiber filter membrane as the substrate. Under high concentrations of ionizing agents (เช่น., Guanidinium chloride or กัวนิดีน isothiocyanate), nucleic acids are adsorbed through hydrogen bonding and electrostatic interactions, while proteins and other impurities are not adsorbed and removed. ต่อมา, the filter membrane with adsorbed nucleic acids is washed to remove proteins and salts. ในที่สุด, low salt buffer solution (เช่น., Buffer TE) or water is used to elute the purified nucleic acids, resulting in high purity suitable for downstream experiments.
• การประมวลผลตัวอย่าง: Stool samples are homogenized in the lysis solution, then further lysed in a high-temperature water bath to release RNA into the solution. Chloroform extraction is employed to remove genomic DNA and impurities. The supernatant is transferred to an alcohol-free binding solution, followed by RNA purification through a column. ในที่สุด, RNA is eluted using RNase Free Water.
• การใช้งาน: The purified RNA is suitable for various downstream experiments such as PCR, Southern hybridization, and enzyme digestion.

ข้อดี

• มีความบริสุทธิ์สูง: Utilizes a unique adsorbent for more efficient removal of inhibitors, ensuring high purity of extracted RNA.
• High Concentration: Achieves maximum extraction of total RNA from stool samples due to its high concentration, maximizing RNA yield.
• อ่อนไหว: Capable of purifying RNA at the level of picograms (PG), ensuring sensitivity in downstream applications.
