| Title |
GM06990_HELP |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
LM-PCR products from HpaII digested DNA
|
| Organism |
Homo sapiens |
| Characteristics |
cell type: Lymphoblastoid
digestive enzyme: HpaII
|
| Growth protocol |
The cells were cultured as recommended by the Coriell repository.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
DNA was isolated using proteinase K digestion, phenol-chloroform extraction, dialysis against 0.2X SSC and concentration by surrounding the dialysis bag with PEG 20,000 to reduce water content by osmosis. The quality of the DNA was checked by gel electrophoresis and spectrophotometry.
|
| Label |
Cy5
|
| Label protocol |
The HELP samples were labeled for microarray analysis as described previously[Selzer, Genes Chromosomes Cancer 44:305–319] using Cy3 or Cy5-conjugated oligonucleotides and random primers.
|
| |
|
| Channel 2 |
| Source name |
LM-PCR products from MspI digested DNA
|
| Organism |
Homo sapiens |
| Characteristics |
cell type: Lymphoblastoid
digestive enzyme: Msp 1
|
| Growth protocol |
The cells were cultured as recommended by the Coriell repository.
|
| Extracted molecule |

|
| Label |
Cy3
|
| Label protocol |
The HELP samples were labeled for microarray analysis as described previously[Selzer, Genes Chromosomes Cancer 44:305–319] using Cy3 or Cy5-conjugated oligonucleotides and random primers.
|
| |
|
| |
| Hybridization protocol |
The HpaII and MspI representations were co-hybridized to the microarray and scanned to quantify the 532 and 635 nm fluorescence at each oligonucleotide on the microarray.

|
| Data processing |
HELP assay data analysis was performed using our published pipeline (Thompson, Reimers, Khulan, Gissot, Richmond, Chen, Zheng, Kim and Greally 2008), an open source resource available through BioConductor (HELP package)
