    Hi Rahul, I was wondering whether this method is working with bacteria cell suspension (I have gram positive bacteria), since if I am not wrong, we need to do lysis first and then DNA extraction? Do you have any lysis methode that can be couple with this DNA extraction methode? My worry whether there is some substance in the lysis methode that can hinder the extraction. I hope you can help me with my question. Thank you and best of luck.

I feel like 1:10 is too small and don’t know how purity of it compare to 1:1 for sequencing. What if I use ratio 1:2 or 1:5? I tried to use less chloroform but would like to be as good purity as possible. Thank you for a great video

    • @RahulPatharkar
      @RahulPatharkar 5 หลายเดือนก่อน

      That is based on my data. The main benefit comes from having much less waste. You can try other ratios. For me all ratios I tested resulted in excellent sequence data. Importantly, almost everything extracted by PCI ends up in the organic:aqueous interphase and a small amount of PCI has a similar surface area for the interphase. Hope this helps.
