WHAT IS DATA REPRODUCIBILITY BETWEEN CustomArray 4X2K AND 12K?
The main difference between CustomArray 12K and 4x2K is usage of two different types of hybridization caps: a standard one for 12K microarrays, and a sectored one for 4x2K microarrays. Fig. 2 shows that usage of the sectored cap doesn’t change CustomArray performance. Pair-wise correlation coefficients (r2 ) between the data obtained with two types of hybridization caps are shown in Fig. 2, and the average r2 is 0.97 (calculated for raw data without normalization and background correction).
