|
| Hybridization protocol |
Following fragmentation, 1 200 ul of hybridization cocktail containing 10 ug of fragmented cRNA placed on chip - Hybridized for 18 hours in GeneChip Hybridization Oven 640 - Washed and stained using 2 strepavidin stains and one antibody stain on GeneChip Fluidics Station 400 for 1.5 hours (GeneChip Expression Analysis Technical Manual- Affymetrix)
|
| Scan protocol |
Arrays were scanned with a GCS300 Scanner (Affymetrix) for images and intensities.
|
| Description |
A/J CS Lung gene expression
|
| Data processing |
Data extraction was processed by Affy GeneChip« Operating Software v1.3 (Affymetrix). Global scaling was equal to 500. Normalization factor was equal to 1. Analysis of differentially expressed transcripts was accomplished using a pairwise comparative analysis (Affy Data Mining Tool v3.1; Affymetrix). 3 sets A/J 1.5 mos CS x 3 sets A/J 1.5 mos Air comparison (1.5 fold cutoff (FC), Mann-Whitney test < 0.05, 6 out of 9 comparisons).
