Hybridization protocol Described in Hu et al., 2005, BioTechniques, 38:121-124 (PMID: 15679094).
Scan protocol Fluorescent array images were collected for both Cy3 and Cy5 with a GenePix 4000B fluorescent scanner and image intensity data were extracted and analyzed with GenePix Pro 5.1 analysis software.
Description UNC980107A
Data processing Data for both channels were Lowess-normalized using the UNC microarray database, and then the log(2) ratio was taken.
