| Title |
P74 dilated cardiomyopathy heart biopsy |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
heart, middle septum
|
| Organism |
Homo sapiens |
| Characteristics |
Dilated cardiomyopathy
|
| Biomaterial provider |
Department of Medicine I, University Hospital Grosshadern, Ludwig-Maximilians-University, Munich, Germany
|
| Treatment protocol |
none
|
| Growth protocol |
none
|
| Extracted molecule |
total RNA |
| Extraction protocol |
total RNA was extracted using Qiagen RNeasy Midi Kit reagents; 2µg total RNA was amplified one round based on T7 RNA Polymerase (Ambion Message Amplification Kit Reagents, 6h IVT)
|
| Label |
Cy3
|
| Label protocol |
direct fluorescent labelling of 2 µg amplified RNA, anneling of 0.5µg Random Primer and reverse-transcribed into cDNA with Superscript III reverse transcriptase for 1h at 42°C in the presence of 0.4 mM dGTP, 0.4 mM dATP, 0.4 mM dTTP, 0.24 mM dCTP, 0.125 mM Cy3-dCTP. After hydrolysis of RNA in 0.2 M NaOH, Cy3-labeled probes were purified with Microcon YM-30 column.

Universal human reference RNA (Stratagene), one round amplified
|
| Organism |
Homo sapiens |
| Characteristics |
common reference sample

| Extracted molecule |
total RNA |
| Extraction protocol |
2µg total RNA was amplified one round based on T7 RNA Polymerase (Ambion Message Amplification Kit Reagents, 6h IVT)
|
| Label |
Cy5
|
| Label protocol |
direct fluorescent labelling of 2 µg amplified RNA, anneling of 0.5µg Random Primer and reverse-transcribed into cDNA with Superscript III reverse transcriptase for 1h at 42°C in the presence of 0.4 mM dGTP, 0.4 mM dATP, 0.4 mM dTTP, 0.24 mM dCTP, 0.125 mM Cy5-dCTP. After hydrolysis of RNA in 0.2 M NaOH, Cy5-labeled probes were purified with Microcon YM-30 column.

| Hybridization protocol |
ch1 and ch2 together are solved in 50 µl 1x DIG-Easy hybridization buffer (Roche Diagnostics, Mannheim, Germany), containing 10x Denhardt’s solution and 2 ng/µl Cot1-DNA (Invitrogen); sample was denaturated at 65°C for 2min, hybridzation of arrays were performed in Corning chambers 14h at 37°C; slides were washed twice in 1xSSC+0.1SDS and once in 0.1xSSC+ 0.1SDS before air pressure drying and scanning.
|
| Scan protocol |
arrays were scanned with the GenePix 4000B microarray scanner and analyzed using GenePix Pro 4.1 software (Axon Instruments)
|
| Description |
P74 dilated cardiomyopathy heart biopsy
|
| Data processing |
raw data processing was performed using ArrayMagic (Buness et al., 2005) and VSN normalization method; after removal of bad quality spots, two hybridizations of this sample were merged; generalized log2 ratios from 30498 cDNA clones were given in the data table.
