Troubleshooting Problem Possible reasons Soutions Low or no yield of genomic DNA Sample stored incorrectly Low amount of cells in the sample Poor cell lysis Poor cell lysis because of insufficient beads beating time Insufficient binding of DNA to column s membrane Ethanol is not added into sample lysate before DNA binding Ethanol and sample lysate did not mix well before DNA binding Poor quality of genomic DNA Store the stool sample at -20 C. Increase the sample size Extend the beads beating time. Make sure that the correct volumes of ethanol (96-100 %) is added into the sample lysate before DNA binding. Make sure that Ethanol and sample lysate have been mixed completely before DNA binding Incorrect preparation of Wash Buffer W1/W2 Ethanol is not added into Wash Buffer when first use The volume or the percentage of ethanol is not correct for adding into Wash Buffer Elution of DNA is not efficient ph of water (ddh2o) for elution is acidic Make sure the ph of ddh2o is between 7.0-8.5. Use Elution Buffer (provided) for elution. Elution Buffer or ddh2o is not completely absorbed by column membrane Make sure that the correct volumes of ethanol (96-100 %) is added into Wash Buffer when first use.
