The Quick-RNA Soil/Fecal Microbe Microprep is an innovative fecal and soil RNA extraction kit designed for the simple, reliable, and rapid isolation of total RNA including small RNAs (>17 nt) from various soil, sludge, sediment and/or fecal samples. The procedure of this fecal and soil RNA extraction kit successfully isolates RNA from tough-to-lyse bacteria, fungi, protozoa (protist), algae, etc. in soil, and host RNA from fecal samples. Samples are added to the ZR BashingBead Lysis Tube with an optimally designed S/F RNA Lysis Buffer where microbes are then lysed by bead beating to extract total RNA. The Zymo-Spin column technology included in this fecal and soil RNA extraction kit allows for quick filtration, genomic DNA removal from sample lysates, and isolation of the RNA. Zymo-Spin III-HRC Spin Filter separates RT-PCR inhibitors (e.g., humic acids, polyphenols, tannins) and the total RNA is concentrated using the Zymo-Spin IC Column with a minimum elution volume of ≥6 µl.
