|
| 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 Manul- Affymetrix)
|
| Scan protocol |
Arrays were scanned with a GCS300 Scanner (Affymetrix) for images and intensities.
|
| Description |
ob/ob Leptin treated 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 ob/ob leptin-treated 1 month x 3 sets ob/ob saline-treated 1 month comparison (1.5 fold cutoff (FC), Mann-Whitney test < 0.05, 6 out of 9 comparisons).
