Figure 2. Collection of Mouse Fecal Samples in Norgen's Fecal DNA Collection and Preservation Mini Tubes. Approximately 30 mg (3-5 droppings) of mouse fecal samples were added to Norgen’s Fecal Collection and Preservation Mini Tubes and briefly vortexed. The preserved samples are ready to ship, or for isolation of DNA using compatible DNA isolation kits. 

Figure 3. Resolution of DNA Isolated from 200 µL Preserved Mouse Fecal Samples using Norgen’s Stool DNA Isolation Kit (Cat. 27600). Briefly, 4-5 drops (<30 mg) of mouse fecal samples were collected using Norgen's Fecal DNA Collection and Preservation Mini Tubes (Cat. 27650). Stool DNA was isolated from the preserved samples using Norgen's Stool DNA Isolation Kit. For evaluation, 10 µL of each 50 µL elution were run on 1X TAE 1.2% agarose gel. Marker = Norgen’s HighRanger DNA Ladder. 

Figure 4. Quality of Mouse Fecal DNA was Evaluated by 16s rDNA Amplification using Real-Time PCR. Two mouse fecal samples (red and blue) were collected and preserved using Norgen’s Fecal DNA Collection and Preservation Mini Tubes, and then 3 µL of DNA was used in 20 µL PCR reaction to detect 16s rDNA. No PCR inhibition was observed, indicating the high quality of DNA from mouse fecal samples for use in downstream applications.
