Sample GSM658930 Query DataSets for GSM658930
Status Public on Dec 08, 2011
Title Pooled (Cy3) v PC3M (wt) (Cy5)
Sample type RNA
 
Channel 1
Source name Pooled knockdowns
Organism Homo sapiens
Characteristics cell line: PC3M
Treatment protocol Short hairpin RNA for RPL19 cloned into a pSilencer™ 4.1-CMV neo (Ambion) expression vector and transfected into PC3-M prostate cells with SiPORT XP-1 reagent (Ambion)
Growth protocol PC3-M prostate cells were grown in RPMI 1640 media containing L-Glutamine (2mM), penicillin (1000units/ml), streptomycin (100μg/ml) and 10% fetal calf serum
Extracted molecule total RNA
Extraction protocol Total RNA was extracted with a Rneasy mini kit (Qiagen) according to manufacturer's instructions
Label Cy3
Label protocol Total RNA was primed with 1.2 μL of T7 Promoter Primer at 65°C for 10 min, reversed transcribed at 40°C for 2 h in the presence of 1mM dNTP mix and then labelled with Cyanine 3-CTP or Cyanine 5-CTP according to Agilent instructions
 
Channel 2
Source name PC3M
Organism Homo sapiens

Treatment protocol Short hairpin RNA for RPL19 cloned into a pSilencer™ 4.1-CMV neo (Ambion) expression vector and transfected into PC3-M prostate cells with SiPORT XP-1 reagent (Ambion)
Growth protocol PC3-M prostate cells were grown in RPMI 1640 media containing L-Glutamine (2mM), penicillin (1000units/ml), streptomycin (100μg/ml) and 10% fetal calf serum
Extracted molecule total RNA
Extraction protocol Total RNA was extracted with a Rneasy mini kit (Qiagen) according to manufacturer's instructions
Label Cy5
Label protocol Total RNA was primed with 1.2 μL of T7 Promoter Primer at 65°C for 10 min, reversed transcribed at 40°C for 2 h in the presence of 1mM dNTP mix and then labelled with Cyanine 3-CTP or Cyanine 5-CTP according to Agilent instructions
 
 
Hybridization protocol Oligoarray control targets and hybridization buffer (Agilent In Situ Hybridization Kit Plus) were added and samples were applied to microarrays enclosed in Agilent microarray hybridization chambers. After hybridization, slides were washed sequentially.
Scan protocol Scanned on an Agilent G2565AA scanner. Images were quantified using Agilent Feature Extraction Software.
Data processing Spatial representations of the hybridization signals were examined to confirm absence of technical artifacts. The distribution of background and foreground signals and pre-normalization MA plots were examined to measure the quality of the hybridization. Low quality spots identified by the Agilent image processing software were not used in the subsequent analyses. Expression signal estimates were derived from the red (cy3) and green (cy5) Agilent Processed Signal data by normalizing using the LOESS algorithm and background correction using a fitted convolution of normal and exponential distributions.
