  • experimental design of ChIP-Seq

    Hi all. I have a question regarding the experimental design of ChIP-Seq. We have cells in two different states, and we would like to compare the binding profile differences between two states. Should we keep the cell amounts used in the ChIP the same?

    By the way, could anyone recommend a tool to analyze the binding profile differences?

    Thanks very much! Any suggestion will be greatly appreciated.

    In general I would say yes, if possible. Since you want to detect differences between states you should keep everything the same between cells except for the "state" variable I.e. randomize possible confounding factors between the two state groups so that the differences can be attributed to the state condition.

    Have a look at these tools (there should be more): MMDiff: quantitative testing for shape changes in ChIP-Seq data sets and DiffBind

      Recent Advances in Sequencing Analysis Tools
      by seqadmin


      The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

      Essential Discoveries and Tools in Epitranscriptomics
      by seqadmin




      The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
