Sample GSM2522881 Query DataSets for GSM2522881
Status Public on Jun 06, 2018
Title Normal_6544
Sample type RNA
Source name Normal sample from prostate cancer patient 6544
Organism Homo sapiens
Characteristics subject status: prostate cancer patient
subject id: patient 6544
ethnic background: African American (AA)
tissue type: normal; matched benign prostate tissue
Growth protocol Tissue samples were obtained from the Human Tissue Acquisition and Pathology Core of the Dan L. Duncan Cancer Center and were collected from fresh radical prostatectomy specimens after obtaining informed consent under an Institutional Review Board approved protocol. Cancer tissues include at least 70% tumor tissue and benign tissues were free of cancer on pathological examination.
Extracted molecule genomic DNA
Extraction protocol DNAs extracted using a Qiagen DNA/RNA mini kit following the manufacturer’s protocol.
Label biotin
Label protocol According to Affymetix protocol.
Hybridization protocol According to Affymetix protocol.
Scan protocol According to Affymetix protocol.
Description 36316
Data processing Copy number values are estimated total copy number (e.g. 2~wild-type). Additional analysis details are as follows: "We fit a linear model to the normalized intensities stratified by the diallic genotype call. The intercept and slope from the linear model are both SNP- and batch-specific. Raw total copy number were estimated using crlmm package in Bioconductor (R 3.0., Bioconductor 2.12), using the default settings. At allele k, marker i, sample j, and batch p, the estimate of allelespecific copy number is computed by subtracting the estimated background from the normalized intensity and scaling by the slope coefficient.
