Sample GSM1723405 Query DataSets for GSM1723405
Status Public on Jun 27, 2015
Title Il1b KO sipnal cord, biological rep1
Sample type RNA
 
Source name Il1b KO lesioned spinal cord, 24 hours after injury
Organism Mus musculus
Characteristics background strain: C57BL/6
genotype/variation: Il1b KO
age: 8-12 weeks
tissue: Spinal cord
Treatment protocol Spinal cord contusion of 50 kdyn was performed using the Infinite Horizon SCI device (Precision Systems & Instrumentation).
Extracted molecule total RNA
Extraction protocol Spinal cord segments of 6 mm-long centered over the lesion were rapidly dissected, frozen in liquid nitrogen, and stored at -80°C until RNA extraction. Total RNA was isolated by TRI Reagent and purified with the GenElute mammalian total RNA miniprep kit (Sigma-Aldrich Canada Ltd.).
Label biotin
Label protocol Two hundred nanograms of total RNA was labeled using the Ambion® WT Expression Kit protocol, as described by the manufacturer (Affymetrix, Santa Clara, CA). The quality of total RNA, cDNA synthesis, cRNA amplification, and cDNA fragmentation was monitored by microcapillary electrophoresis (Bioanalyzer 2100, Agilent Technologies).
 
Hybridization protocol Five µg of fragmented single-stranded cDNA was hybridized for 16 hours at 45°C with constant rotation on a GeneChip® Mouse Gene 1.0 ST Array (Affymetrix). After hybridization, were processed using the Affymetrix GeneChip Fluidic Station 450 (protocol FS450_0007).
Scan protocol Microarrays were scanned using a GeneChip Scanner 3000 7G (Affymetrix)
Data processing Images were extracted with the GeneChip Operating Software (Affymetrix GCOS v1.4). Quality control of microarrays was performed using the AffyQCReport software. Background subtraction and normalization of probe set intensities was performed using the method of Robust Multiarray Analysis (RMA). Data analysis was performed using the AffylmGUI Graphical User Interface for the LIMMA microarray package (Wettenhall et al., 2006), and Partek Genomics Suite (Partek Incorporated)
