  • ATAC-seq - cell/material loss during wash steps

    Hi,

    I am doing ATAC-seq on sorted lymphocytes, but I find that I always need more than the recommended 6 extra PCR cycles (11 total) to reach one third maximal fluorescence on the qPCR, even with 100,000 cells. I think that I am probably losing cells/material during the wash steps. I was wondering whether anyone has any tips for removing the supernatant without dislodging the pellet too much? I am making sure to remove the supernatant from the opposite side of the eppendorf to the pellet. Also, I have a question regarding FBS. Is it ok to sort into media containing FBS, as someone else mentioned in a post that their library was contaminated with bovine DNA?

    Thanks for any advice!

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
