Principle
TheHiPure silica gel column uses a high binding ability glass fiber filtermembrane as the substrate. Under the condition of high concentration ofionizing agent (such as Guanidinium chloride or guanidine isothiocyanate), thefilter membrane can adsorb nucleic acid through hydrogen bonding andelectrostatic and other physical factors, while protein or other impurities arenot adsorbed and removed. The filter membrane that has adsorbed nucleic acidsis washed to remove proteins and salts. Finally, low salt buffer solution (suchas Buffer TE) or water can be used to wash out the nucleic acids adsorbed onthe filter membrane. The obtained nucleic acid has high purity and can bedirectly used in various downstream experiments.
The stoolsamples are homogenized in the lysis solution, further lysed in ahigh-temperature water bath, and RNA is released into the lysis solution.Chloroform extraction removes genomic DNA and impurities, transfers thesupernatant to an alcohol free binding solution, purifies RNA through a column,and finally elutes RNA with RNase Free Water. The purified RNA can be directlyused for experiments such as PCR, Southern hybridization, and enzyme digestion.
Advantages
-
High purity - unique adsorbent for more efficient removal of inhibitors
-
High concentration - maximum extraction of total RNA from stool samples
-
Sensitive - RNA can be purified at the level of PG

Storage and Stability
The kitcomponents can be stored at room temperature (15–25°C) and are stable for 18months under these conditions. At low temperatures, Buffer SPL may formprecipitates, dissolve it by 55°C water bath. After receiving the product,Buffer PHC should be stored at 2-8°C.
