Previously used Bioline kit, have tried QIAmp DNA stool mini kit but am getting really poor yield, can anyone recommend any other kits or methods?

We have a reagent AquaPrecipi for fecal PCR inhibitor removal. Fecal DNA is ready for PCR after it is precipitated with AquaPrecipi and ethanol. Fecal DNA analysis is an excellent noninvasive method for wildfile, GI infections, GI cancers, and genotyping studies.

I have just recently ordered a sample kit from Zymo Research (with 5 reactions) and it worked fine for me. The sample kit is for free.

Hi AquaPlasmid--

Can you clarify, is this for removing inhibitors, post-extraction? Cause I got a lot of failed fecal extractions with inhibitors, but dilution doesn't help because the template copies are already so low/degraded, I would love a way to rescue them...

Thanks
Kim
