title: GSM3045197: ciPSC-CM; Pan troglodytes; RNA-Seq
library_construction_protocol: For RNA-seq, RNA was isolated using miRNeasy kit (Qiagen) following the manufacture's protocol. For ATAC-seq, 100,000 cells were centrifuged 500 g for 5 min at room temperature. The cell pellet was resuspended in 50 ml lysis buffer (10 mM Tris–Cl, pH 7.4, 10 mM NaCl, 3 mM MgCl2, 0.01% Igepal CA-630) and centrifuged immediately 500 g for 10 min at 4°C. The cell pellet was resuspended in 50 ml transposase mixture (25 ul 2×TD buffer, 22.5 μl dH2O, and 2.5 μl Illumina Tn5 transposase or with final concentration of 100 nM Atto-590-labeled in-house Tn5) and incubated at 37°C for 30 min. After transposition, the mixture was purified with the Qiagen Mini-purification kit and eluted in 10 ul Qiagen EB elution buffer. For transgenic BANCR embryos plasmid vector construction (pRP[Exp]-BetaMHC>hBANCR) and purification, pronuclear plasmid injection of FVB embryos, harvesting and genotyping of E16 embryos were performed by Cyagen Biosciences (Santa Clara, CA,USA). Total RNA was isolated from extracted embryo hearts that were plasmid positive (n=2) or negative (n=2). Total RNA was submitted to a core facility (Stanford Functional Genomics) for library preparation and Illumina sequencing. For ATAC-seq, sequencing libraries were prepared following the original ATAC-seq protocol (Buenrostro, J. D. et al. Nat Methods 10, 1213-1218 (2013)). The HiChIP protocol was performed as previously described (Mumbach, M. R. et al. Nat Methods 13, 919-922 (2016)).
