| Title |
A244k-2040 |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Normal whole-spleen tissue
|
| Organism |
Mus musculus |
| Characteristics |
strain: FVB
tissue: Spleen
|
| Biomaterial provider |
UNC Chapel Hill
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Mouse DNA was isolated from either small tissue pellets (20-30 ug) or ethanol precipitated RNA flow through solution. Pellet digestion and DNA isolation steps were in accord with the DNAeasy Mini Kit protocol.
|
| Label |
Cy3
|
| Label protocol |
0.9 ug of genomic DNA digested with Alu I and Rsa I restriction enzymes at 37 degrees Celsius for 2 hours. The reaction was stopped by heating the mixture to 65 degrees Celsius for 20 minutes. Each fragment was then randomly primed at 95 degrees celsius for 3 minutes. Cy3 and Cy5 modified nucleotides were then incorporated by the Large Fragment of DNA Polymerase I (exo klenow fragment) at 37 degrees Celsius for 2 hours.

| Organism |
Mus musculus |
| Characteristics |
strain: Mixed
mouse class: Rb1

| Hybridization protocol |
Appropriate cyanine 5- and cyanine 3-labeled DNA sample pairs were combined and then mixed with mouse Cot-1 DNA, Agilent 10X aCGH Blocking Agent, and Agilent 2X Hi-RPM Hybridization Buffer. The labeled target solution was hybridized to Agilent's 244a Mouse Genome CGH microarray (G4415A) using SureHyb chambers. After hybridization the microarrays were washed and dried according to the procedures described in Agilent's protocol.
|
| Scan protocol |
Each microarray slide was scanned at a resolution of 5 um on Agilent G2539A scanner under Scan Control software version A.8.1.3. Spot intensity values were obtained using Agilent aCGH version 4.1 -FE 10 Default Protocol under Agilent Feature Extraction software version 10.1.

| Description |
matches to expression sample: Mixed_Rb_7.Oct22.07_UHNC
|
| Data processing |
Data for both channels were Lowess-normalized and then log(2) ratio was taken
