design: DNA libraries were prepared using a MGIEasy Universal DNA Library Prep Set. DNA was fragmented using a Covaris S220 ultrasonicator. DNA libraries were washed with Agencourt AMPure XP. Concentrations of DNA and DNA libraries were measured by a Qubit Flex instrument with the use of the dsDNA HS Assay Kit.The DNA library quality control was performed using a Bioanalyzer 2100 and a High Sensitivity DNA kit.
