	Ribosylation incubation period					p-values
	Control	2 days	4 days	6 days	8 days	Ribosylated vs 0-day control
Annulus fibrosus [ms]	97.6 (11.1)	99.5 (3.47)	99.7 (13.3)	103 (11.5)	83.3 (9.96)	p = 0.912
Nucleus pulposus [ms]	149 (5.35)	141 (7.19)	137^* (6.01)	127^* (3.73)	123^* (8.87)	*p < 0.001*

Denotes significantly lower than the control as determined by the Fisher’s LSD test.
