a Cell disruption efficiency, determined by the fraction of disrupted cells against total number of intact cells, was quantified at different cell concentrations. b After the centrifugation steps, total protein yield was determined accordingly. These experiments were conducted using HEK293 cells. Results were plotted as mean ± SD (n = 3 independent experiments, **P < 0.01, ***P < 0.001)
