Sample GSM940224 Query DataSets for GSM940224
Status Public on Aug 24, 2012
Title Pediatric Astrocytoma III (anaplastic astrocytoma) A3-7432
Sample type RNA
Source name Pediatric Astrocytoma Tumor Sample 12
Organism Homo sapiens
Characteristics tumor grade: III (anaplastic astrocytoma)
tissue: Pediatric Astrocytoma Tumor
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from flash-frozen pediatric astrocytoma samples. Total cellular RNA was extracted using Qiagen's RNA isolation kit according to manufacturer's protocol, and genomic DNA contamination was removed by an on-column Dnase digestion step. RNA was quantified using a NanoDrop-1000 spectrophotometer and quality was monitored with the Agilent 2100 Bioanalyzer
Label Cy3
Label protocol standard Agilent protocol
Hybridization protocol standard Agilent protocol
Scan protocol standard Agilent protocol
Data processing Cy3 median signal intensities were recovered from Agilent Feature Extraction software output, converted to Log2 scale and quantile normalized between arrays, and duplicated probe signals were merged by taking their median values (see series normalized data file).
