| Hybridization protocol |
7_D20_V1 Cy5 / 5_D15_V1 Cy3 : 20pmol. (Hybridization_Protocol.txt) Hybridization Protocol: CATMA slides (Corning Microarray Technology, CORNING) are pretreated in the prehybridisation solution (1 % BSA, 0.1 SDS, 5X SSC ) at 42°C for 60 min. They are dipped a couple of times in distilled water at room temperature, then in isopropanol and dried immediately by compressed nitrogen stream. Slides were placed in Corning hybridization chambers with a 25x60 lifterslip and 10ul of distilled water for each groove. The target was diluted to a final volume of 60 µL as follows 15µl of purified, labeled cDNA, 15 µl of 4X Hybridization Buffer ( 20X SDS, 0.4 % SDS), 30 µL formamide. The target mixture is heated for 3 min at 95°C, put on ice for 30 sec and centrifuged to remove dust for 1 min. The target mixture was put on the chip as quickly as possible. The microarray is sealed in a chamber and submerged in a 42°C water bath for approximately 16 h. The microarray is washed for 4 min in 1xSSC, 0.2% SDS (42°C); 4 min in 0.1x SSC, 0.2% SDS (RT); 4 min in 0.1x SSC, 0.2% SDS (RT); 4 min in 0.1x SSC (RT); dipped a few times in distilled water and dried immediately by compressed nitrogen stream.

| Description |
Delineation of the metabolic pathways involved in maize endosperm vitreousness.
|
| Data processing |
For each array, the raw data comprised the logarithm of median feature pixel intensity at wavelengths Cy5 (red) and Cy3 (green).For each array, a global intensity-dependent normalization using the loess procedure (Yang et al., 2002) was performed to correct the dye bias.Log-ratios are then averaged over the duplicate probes to get a value per gene.
