Sample GSM5121296 Query DataSets for GSM5121296
Status Public on Jul 06, 2021
Title RB24 (expression)
Sample type RNA
Source name retinoblastoma sample RB24
Organism Homo sapiens
Characteristics geo dataset serie: SAMPLE 17
batch: RB01
tissue: retinoblastoma
Growth protocol Immediately following enucleation, a needle was inserted through the anterior chamber of the eye to extract a tumor sample by aspiration. The tumor specimen was placed in RPMI medium on ice, cells were re-suspended, counted and separated into two tubes (for DNA and RNA preparation). The tubes were then centrifuged to remove all media and snap frozen for later extraction.
Extracted molecule total RNA
Extraction protocol Tumor RNA was extracted using Qiazol (Qiagen, Courtaboeuf, France) according to the manufacturer instructions and purified using miRNeasy Mini kit (Qiagen).
Label biotin
Label protocol 100ng of total RNA were amplified to produced biotinylated complementary RNAs, as recommended by Affymetrix.
Hybridization protocol Affymetrix microarrays were hybridized with 10µg of biotinylated cRNA according the supplier recommendations. Microarrays were washed and stained using FS450 fluidics upon a protocol provided by Affymetrix, corresponding to the U133plus 2.0 arrays
Scan protocol Microarrays were scanned using a 7G, Affymetrix GCS3000 scanner, raw data were acquired with Affymetrix Genechip Command Console.
Description Gene expression data from retinoblastoma samples
Data processing Signal reconstruction was performed with the RMA algorithm as implemented in Bioconductor affy package on R statistical software using the Dai custom CDF package: HGU133Plus2_Hs_ENTREZG, Brainarray Custom CDF EntrezG version 23, Batch effects were corrected with the help of the bioconductor package SVA,
