Variable analysis
- Excised peritoneal membranes
- Transposase-accessible chromatin (ATAC-seq)
- Excised peritoneal membranes were immediately frozen in liquid nitrogen and stored at −80°C until use.
- Tissues were diced and ground to a fine powder with intermittent addition of liquid nitrogen.
- 100,000 nuclei per sample were isolated using an iodixanol gradient.
- ATAC-seq was performed according to the original protocol (42 (link)) using a Nextera DNA sample preparation kit (Illumina, FC-121-1030).
- After amplification, library DNA was isolated (Qiagen MinElute kit), size selected, and sequenced (Illumina HiSeq 4000).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
