Sample GSM1383832 Query DataSets for GSM1383832
Status Public on Aug 28, 2015
Title PDAC55
Sample type RNA
 
Source name frozen pancreatic tissue
Organism Homo sapiens
Characteristics overall survival (month): 24.2333333333333
vital.status: ALIVE
Stage: 2B
Extracted molecule total RNA
Extraction protocol Samples are processed in parallel in 96-well plates to minimize potential variation. Reaction purification is achieved using magnetic binding beads for cDNA and Qiagen RNeasy kits for cRNA purification.
Label biotin
Label protocol The final in vitro transcription incorporates biotin moieties that are later labeled with phycoerythrin. After amplification, samples are put through a controlled fragmentation to improve hybridization sensitivity and consistency. The labeled molecules are biotinylated-cRNA.
 
Hybridization protocol GeneChip microarrays are loaded with the fragmented target sample/hybridization buffer mix using standard manual techniques. Arrays are hybridized for 18 hours at 45C with vigorous mixing. Unbound sample is removed and staining is accomplished through the binding of streptavidin conjugated phycoerythrin to the hybridized target. Excess label is removed. Washing and staining steps are performed by the Affymetrix FS450 fluidics station using standard protocols.
Scan protocol Arrays are scanned using a GeneChip Scanner 3000 7G with a 48 array autoloader. The scanner maintains the optimal temperature for the arrays prior to and during scanning.
Description frozen pancreatic tissue
Data processing Expression values were calculated using the robust multi-array average (RMA) algorithm
