Sample GSM406322 Query DataSets for GSM406322
Status Public on May 21, 2009
Title LPS Vs. Normal (Sample 1 dye swap)
Sample type RNA
 
Channel 1
Source name LPS
Organism Holothuria glaberrima
Characteristics immuno-activated: Yes (LPS)
regeneration stage: n/a
Treatment protocol After n days (3, 7 or 14) of regeneration the tissues were colected and mRNA was extracted and labeled with Cy3 and Cy5 depending on the comparisons.
Growth protocol ESTs from regenerating and normal tissues were obtained from cDNA library construction from different stages of regeneration.
Extracted molecule total RNA
Extraction protocol Total RNA extracted using Trizol following manufacturer's instructions (Quiagen)
Label Cy3
Label protocol 1ug of polyA RNA was amplified using T7 promoter and reverse transcribed with 0.1M DTT, 10 mM dNTPmix, 5X 1st strand buffer, 50% PEG, inorganic phosphatase, Rnase Out and MMLV-RT enzimes. labeling was performed using T7 RNA polymerase and Cy3 and Cy5 CTP during 2 hours at 40º C.
After amplification-labeling reaction samples were purified with Qiagen's RNeasy spin columns. Amplified and labeled cRNAs were quantified. Samples over 150ng/ul amplification and dye incorporation larger than 13 were used for hybridization (much better yield than minimun recomended by Agilent)
 
Channel 2
Source name Normal
Organism Holothuria glaberrima
Characteristics regeneration stage: Normal
immuno-activated: No
Treatment protocol After n days (3, 7 or 14) of regeneration the tissues were colected and mRNA was extracted and labeled with Cy3 and Cy5 depending on the comparisons.
Growth protocol ESTs from regenerating and normal tissues were obtained from cDNA library construction from different stages of regeneration.
Extracted molecule total RNA
Extraction protocol Total RNA extracted using Trizol following manufacturer's instructions (Quiagen)
Label Cy5
Label protocol 1ug of polyA RNA was amplified using T7 promoter and reverse transcribed with 0.1M DTT, 10 mM dNTPmix, 5X 1st strand buffer, 50% PEG, inorganic phosphatase, Rnase Out and MMLV-RT enzimes. labeling was performed using T7 RNA polymerase and Cy3 and Cy5 CTP during 2 hours at 40º C.
After amplification-labeling reaction samples were purified with Qiagen's RNeasy spin columns. Amplified and labeled cRNAs were quantified. Samples over 150ng/ul amplification and dye incorporation larger than 13 were used for hybridization (much better yield than minimun recomended by Agilent)
 
 
Hybridization protocol Samples were prepared as manufacturer's recommendations using the fragmentation step and hybridized at 65°C for 17hours in Agilent SureHyb-enabled hybridization chambers. After hybridization, slides were washed sequential
Scan protocol Slides were scaned on an Agilent G2505B Scanner. Resolution used =5um
Images were quantified using Agilent Feature Extraction Software (version A9.5.3.1)
Description Biological replicate with dye swap conditions
dpe: days post evisceration
Data processing Agilent Feature Extraction Software (v 9.5.3.1) was used for background substraction and LOWES normalization.
Statistical analyzes were also performed with two softwares: 1) using R (BioConductor package) using the original Feature extractor output files and 2) Using GenePix and Acuity (Axon Lab.) for differentially expressed genes and clustering (hierarchical and non hierarchical) analyzes
