Sample GSM805422 Query DataSets for GSM805422
Status Public on Apr 16, 2012
Title Au-NP Replicate1
Sample type RNA
 
Source name whole worms wild type
Organism Caenorhabditis elegans
Characteristics strain: N2
treatment: gold nanoparticles
developmental stage: L3
Treatment protocol LC10 at 5.9 mg/L of 4-nm citrate coated Au-NP for 12 hrs in 50% K-medium, the exposure solutions were replaced with 50% K-medium and left for another 12 hrs.
Growth protocol C. elegans were maintained on NGM plates at 20 ⁰C. Age-synchronized nematodes at L3 stage were used for the experiment
Extracted molecule total RNA
Extraction protocol RNA was extracted from each of the replicates using Trizol (Invitrogen) followed by purification with Qiagen RNeasy Kit (Qiagen, Chatsworth, CA). Repeated freeze-thaw cycles (at -80 and 37⁰C) were used to lyse the cells.
Label biotin
Label protocol Biotinylated cRNA was prepared from 2 microgram total RNA according to standard protocol in the Affymetrix GeneChip Expression Analysis Manual.
 
Hybridization protocol Following Fragmentation, 13 microgram of cRNA were hybridized to Affymetrix C. elegans genome array for 16 hours. GeneChips were washed and stained in the Affymetrix Fluidics Station 450.
Scan protocol The microarray chips were scanned using Affymetrix GCS 3000 7G scanner
Data processing The data were normalized using RMA algorithm followed by quantile normalization implemented in Partek Genomics Suite 6.4 (Partek, Inc, St Louis, MO).
