ATAC-seq of MIN6 cells
Library Strategy: ATAC-seq. ATAC-seq libraries for all samples were prepared as detailed in Buenrostro, J. D., Giresi, P. G., Zaba, L. C., Chang, H. Y. & Greenleaf, W. J. Transposition of native chromatin for fast and sensitive epigenomic profiling of open chromatin, DNA-binding proteins and nucleosome position. Nat Meth 10, 1213_1218 (2013). Approximately 250,000 INS-1(832/13) cells, and 50,000 MIN6 cells were transposed.
