Coefficient of Variation (CV) for Each Inflammatory Gene in a Colonic Region For Healthy Controls

Inflammatory Gene	Ascending Colon	Transverse Colon	Descending Colon	Rectum
IL-1β	40%	48%	50%	29%
TNFα	40%	41%	29%	42%
IL-6	50%	54%	42%	55%
IL-8	66%	71%	40%	40%
MMP-3	92%	88%	69%	85%
S100A8	56%	49%	64%	64%
IP-10	52%	59%	44%	39%
CXCL-13	91%	46%	92%	53%

The coefficient of variation (CV) was calculated for each gene for biopsies from each region of the colon in healthy controls. The coefficient of variation was different for each inflammatory gene and differed based on the region of the colon that was sampled.
