LLLT causes cyanide disassociation from C-ox. U2OS cells were treated with $100\text{-}\mu \mathrm{M}$ sodium cyanide, and then some cells were immediately exposed to LLLT for 30 min. Media and cell extract samples were harvested and cyanide concentration was determined. Data represent the $\text{mean}\pm \mathrm{SEM}$ of at least three separate experiments with $n=2$ per experiment. **$P<0.01$ compared to untreated control.

Treatment condition	Media cyanide concentration ($\mu \mathrm{M}$)	Cellular cyanide concentration ($\mu \mathrm{M}$)
Control	$5.82\pm 0.10$	$4.38\pm 0.40$
Laser 652 nm	$5.82\pm 0.12$	$3.04\pm 0.12$**
Laser 806 nm	$5.84\pm 0.37$	$3.05\pm 0.29$**
LED 637 nm	$5.80\pm 0.14$	$2.88\pm 0.22$**
