It depends on the objective of the extracted DNA.I like Qiagen kits but in most cases, I have to do trial and error process to optimize the kit for my research.
You need to try the original procedure and you move from there.
Good luck,
It really depends on your objective (microsatellites, mtDNA, etc.) and, of course, your sample. You are already using non-invasive samples, therefore you are already expecting DNA with lower quality, yield and concentration. Additionally, faeces can also have different DNA outputs depending on their preservation, before and after collection. Taking this into account, most companies, including Qiagen, have specialised kits for this kind of extractions, but you also have to be more careful with contaminations. If you do not have good results with a standard kit, either you try to optimize the protocol or you try more specialised but usually more expensive kits.
Good luck!
Hello dear, We use Banglore Genei kits for DNA isolation from blood samples. Banglore Genei Teaching kits for Msc Students.All results were good.
I used Qiagen stool kit for isolating dna from herbivore feces. Feces was conserved in ethanol. I did some pre-treatment before processing the sample following provided protocol. So far, I got at least 75% successful amplification both with d-loop and microsats.
