Figure 1. The cytotoxicity of ultrasound (US) irradiation on myotubes was investigated.

Figure 1.

Viability of myotubes was assessed by (A) MTT assay and (B) Zombie Red staining at 24 hr after US irradiation. (red: Zombie Red, blue: DAPI). (C) Total protein content was measured by the Bradford method at 24 hr after US irradiation. (D) Energy metabolism in C2C12 myotubes was measured by citrate synthase assay at 24 hr after US irradiation. The US intensities of 1.0 W/cm2, 2.0 W/cm2, and 3.0 W/cm2 were tested. Data are expressed as mean ± SEM. n=4.
