| Title |
Polyploid TGCs day E9.5_aCGH_Replicate 2 |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
murine E9.5 polyploid TGCs
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6J
cell population: polyploid TGCs
developmental stage: E9.5
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Embryonic cells and purified TGCs from 14 implantation sites (replicate 2) were lysed in CHIP buffer (50mM HEPES pH. 7.5; 140mM NaCl; 1mM EDTA; 1% Triton-X100; 0.1% Na deoxycholate), sonicated, and treated with proteinase K and RNAse. DNA was isolated following standard phenol:chloroform extraction.
|
| Label |
Cy5
|
| Label protocol |
Genomic DNA samples were differentially labeled with Invitrogen’s BioPrime Total for Agilent aCGH labeling kit.

| Label |
Cy3
|
| Label protocol |
Genomic DNA samples were differentially labeled with Invitrogen’s BioPrime Total for Agilent aCGH labeling kit.
|
| |
|
| |
| Hybridization protocol |
Samples were co-hybridized to a 1-million probe custom tiling array designed for C57BL/6J (Agilent-027414).
|
| Scan protocol |
Slides were washed and scanned using an Agilent microarray scanner.
|
| Description |
Biological replicate 2 of 2; hand-dissected E9.5 polyploid TGCs.
|
| Data processing |
Using the Ringo package in R, probes were median-normalized and smoothened by running medians prior to calling under-replicated or amplified regions, defined by at least 5 adjacent probes with a fold change (copy number vs. overall ploidy) greater than 1.3. Microarrays were also converted into Nimblegen format and processed by MA2C software.
