Comparability of Microarray Data between Amplified and Non Amplified RNA in Colorectal Carcinoma

Table 1

Pearson correlations of microarray signals and detection 𝑃-values between non amplified (NA) and amplified (PA) RNA samples from four colorectal carcinoma specimens. The RNA was isolated from identical samples and underwent either amplification or no amplification prior to microarray hybridization.

Samples	Signals	Detection 𝑃-value
1 NA versus 1 PA	0.91	.81
2 NA versus 2 PA	0.89	.75
3 NA versus 3 PA	0.86	.79
4 NA versus 4 PA	0.91	.81
