library_construction_protocol: Tissue was homogenized in 700 µL of homogenization buffer (320 mM sucrose, 5 mM CaCl2, 3 mM Mg(CH3COO)2, 10 mM Tris HCl [pH 7.8], 0.1 mM EDTA [pH 8.0], 0.1% NP-40, 1 mM β-mercaptoethanol, and 0.4 U/µL RNase inhibitor) with a 2 mL tissue grinder. Tissue was filtered through a 40 µm cell strainer and mixed with 450 µL solution of 50% OptiPrep density gradient medium, 5 mM CaCl2, 3 mM Mg(CH3COO)2, 10 mM Tris HCl [pH 7.8], 0.1 mM EDTA [pH 8.0], and 1 mM β-mercaptoethanol.  The mixture was then pipetted onto an OptiPrep density gradient containing 750 µL of 30% OptiPrep Solution (134 mM sucrose, 5 mM CaCl2, 3 mM Mg(CH3COO)2, 10 mM Tris HCl [pH 7.8], 0.1 mM EDTA [pH 8.0], 1 mM β-mercaptoethanol, 0.04% NP-40, and 0.17 U/µL RNase Inhibitor) on top of 300 µL of 40% OptiPrep Solution inside a microcentrifuge tube. Nuclei were pelleted at the interface of the OptiPrep density gradient by centrifugation. Nuclei were washed three times with 2% BSA and the nuclear pellet was re-suspended in 100 µL of 2% BSA. Libraries were constructed according to the 10x Genomics Single Cell Expression v3 User Manual.
