| 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 |
UNC040095B
|
| Data processing |
Data for both channels were Lowess-normalized using the UNC microarray database, and then the log(2) ratio was taken.
