Table 1 Inter-chip variability

From: Dietary exposure to soy or whey proteins alters colonic global gene expression profiles during rat colon tumorigenesis

Diet group Number of arrays TFC (%)*
CAS 3 0.252 ± 0.138
WPH 3 0.369 ± 0.025
SPI 3 0.570 ± 0.165
  1. *TFC (Total false change) = false change rate (decreased category) + false change rate (increased category), as described in ref. 28; TFC reported as mean ± SEM, TFC should be no more than 2% (Affymetrix).
