Gene expression profiling of whole blood: Comparison of target preparation methods for accurate and reproducible microarray analysis

Table 3 Correlation (r) of array data from donor RNA extracted from fresh versus frozen PAXgene tubes

Donor	Method 1 No depletion_Affy	Method 2 Globin PNAs_Affy	Method 3 GLOBINclear_Affy	Method 4 No depletion_NuGEN
A	0.953	0.991	0.959	0.979
C	0.989	0.993	0.959	0.981
D	0.996	0.992	0.988	0.993

Pearson correlation coefficients for each within-method comparison are reported. Microarray data was analyzed and scaled with MAS 5.0.
