| Title |
7113_Lung developed PGD |
| Sample type |
RNA |
| |
|
| Source name |
lung biopsies from the anterior right middle lobe or lingula immediately prior to cold-flushing.
|
| Organism |
Homo sapiens |
| Characteristics |
P/F ratio at T0:82
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Single isolates of donor lung samples were homogenised in the presence of RNAzolB and finally dissolved in RNase-free H2O. 25 micro-grams of total RNA was treated with DNase using the Qiagen RNase-free DNase kit and samples were further purified using RNeasy spin columns (Qiagen, Valencia, CA). Total RNA treated with DNase was dissolved in RNase-free H2O to a final concentration of 0.2 g/l. RNA quality was assessed by 1% agarose gel electrophoresis in the presence of ethidium bromide. Samples that did not reveal intact and approximately equal 18S and 28S ribosomal bands were excluded from further study.

| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 25 micrograms total RNA.
|
| |
|
| Hybridization protocol |
Following fragmentation, 10 micrograms of cRNA were hybridized for 16 hr at 45C on GeneChip Human Genome Array (HGU133Av2). GeneChips were washed and stained in the Affymetrix Fluidics Station 450.
|
| Scan protocol |
Affymetrix GeneArray scanner 3000. Image analysis was performed with the Affymetrix GeneChip software.
|
| Description |
Samples were immediately snap-frozen in liquid nitrogen and then stored in a -70° Celsius freezer until used for analysis. An area of lung tissue approximately 1 x 1 cm was isolated and excised using 2 staple lines from a 30 mm EndoGIA stapler (US Surgical, Norwalk, CT).
|
| Data processing |
The data were normalised using gcRMA. Log2-transformed data.
