HepG2 cells (6 × 106) were mixed with 10 μg pLV-UBI-MCS-3Flag-EF1-EGFP-PER1 and 10
μg pLV-UBI-MCS-3Flag-EF1-EGFP-PER2 (Transheep, Shanghai, China) in Opti-MEM (Gibco). The
mixture was placed in 2-mm gap cuvettes. The cell suspensions were electroporated at 170 V for 5 ms
using a NEPA21 electroporator (Nepa Gene).

For electroporation, cells were washed twice with ice-cold phosphate-buffered saline (PBS) and resuspended at a density of 1.5 × 107 cells/ml. Subsequently, 400 μl of the cell suspension was mixed with 5 μg RNA and transferred to a 2-mm electroporation cuvette (Bio-Rad). The following parameters were used for square wave electroporation: 900 V, 100 μs, and 2 pulses within 5 s (Gene Pulser Xcell electroporation system; Bio-Rad).
