GSM6122975: Retina 4 Hi-C; Homo sapiens; Hi-C
Freshly dissected human retina tissue was crosslinked with 1% formaldehyde in PBS for 10 min, quenched with 125 mM glycine for 5 min and frozen until use for Hi-C experiments. Before processing for Hi-C, samples were crosslinked again in 2% formaldehyde for 10 minutes, then quenched with 125 mM glycine 5 min. For HCT116 cell line (ATCC, VA, USA), 7x106 cells were crosslinked with 2% formaldehyde for 10 min, quenched for 5 min with stop solution I, lysed, and processed for Hi-C using ARIMA-Hi-C kit. Hi-C was performed on isolated nuclei using Arima-Hi-C kit (Arima Genomics, CA, USA) and Hyper Prep DNA-seq library prep kit (KK8502; Kapa Biosciences, MA, USA), following the manufacturers' instructions. The libraries were sequenced on HiSeq 2500 platform (Illumina, CA, USA) at a read length of 101 to 126 base pairs and approximately 600 million read pairs per sample.
