HiPure Soil RNA Kit is suitable for extracting high-purity microbial total RNA from soil samples. The kit adopts silica gel column purification technology and original humic acid adsorbent technology. It is suitable for extracting high-yield and high-purity total RNA from various soil samples, such as forest soil, grassland soil, mining soil, sediment and so on. The obtained RNA can be directly used in RT-PCR, Northern blot, poly-A + purification, nucleic acid protection and in vitro translation.

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

Storage and Stability
Buffer PHC 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 dry at room temperature (15–25°C) and are stable for at least 18 months under theseconditions.The entire kit can be stored at 2–8°C, but in this case buffers should be redissolvedbefore use. Make sure that all buffers are at room temperature when used.
