Stratagene Universal Human Reference RNA
|
Organism |
Homo sapiens |
Characteristics |
sample type: Reference RNA Pool
|
Treatment protocol |
Human tissue specimens were surgically excised and snap frozen in liquid nitrogen
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was extracted from 10x 15 μm sections using Trizol™ according to Invitrogen's instructions
|
Label |
Cy3
|
Label protocol |
Custom automated version of the aminoallyl MessageAmp II kit from Ambion. Microarrays are incubated at 40°C for 48 hours in a rotating carousel. Hybridizations to custom Agilent microarrays are completed as previously described (Hughes et al.Nat Biotech (2001), 19(4):342-7). Microarrays are washed to remove non-specific hybridized sample. Afterwards, microarrays are dried in an ozone-free nitrogen chamber.

Hybridization protocol |
Microarrays are incubated at 40°C for 48 hours in a rotating carousel. Hybridizations to custom Agilent microarrays are completed as previously described (Hughes et al.Nat Biotech (2001), 19(4):342-7). Microarrays are washed to remove non-specific hybridized sample.

|
Scan protocol |
Microarrays are scanned using the Agilent LP2 laser scanner. The scanner output is a Tiff file, which contains the quantitative hybridization data from each individual microarray. The Tiff files are then processed using Rosetta custom feature extraction software.

Description |
Individual esophageal adenocarcinoma tissue specimen
|
Data processing |
Data were processed using the Rosetta Resolver® system. Rosetta's custom feature extraction software performs error modeling before data are loaded into the Resolver system. The Resolver system performs a squeeze operation that combines replicates of the same sequence in an array while applying error weighting. The error weighting consists of adjusting for additive and multiplicative noise. A P-value is generated and propagated throughout the system. The P-value represents the probability that a gene is expressed. The Resolver system allows users to set thresholds, below which genes of a P-value are considered to be significantly expressed. The Resolver system also combines multiple arrays using a squeezing process. If multiple spots reference one sequence, summarization is performed using an error-weighted average as described in Roland Stoughton and Hongyue Dai, Statistical Combining of Cell Expression Profiles. US Patent #6,351,712, February 26, 2002.
