Sample GSM60450 Query DataSets for GSM60450
Status Public on Aug 10, 2005
Title hMSCsVsLiver2
Sample type RNA
 
Channel 1
Source name Untreated Mesenchymal Stem Cells
Organism Homo sapiens
Characteristics Tissue: isolated hMSC
Gender: male
Age: comprised between 35 and 50
Donor #2
Extracted molecule total RNA
Extraction protocol RNeasy Mini kit (Qiagen)
Label Cy3

Channel 2
Source name Adult liver
Organism Homo sapiens
Characteristics Human liver
Chemicon cat.Nr 562
Biomaterial provider Chemicon
Extracted molecule total RNA

Label protocol Representational amplification of mRNA and fluorescent labelling was carried out using Ambion’s Amino Allyl MessageAmp aRNA kit and NHS ester Cy3 and Cy5 conjugated fluorescent dyes (Amersham Bioscience) following the protocol suggested by the supplier
 
 
Hybridization protocol The arrays were pre-blocked in hybridization buffer (5X SSC; 0.1%SDS; 0.2 mg/ml Torula Yeast RNA; 5X Denhardt's solution; 25% formamide) for 2 hours. 120 pmol of each dye-labeled aRNA sample, diluted in 100 µl of hybridization buffer were pre-denatured for 5 minutes at 65°C and then applied on the glass slide. A glass coverslip was used to uniformly spread the sample solution. Incubation was carried on for 24 hours at 48°C in a humid chamber and was followed by 6 washing steps with lowering concentration of SSC and SDS
Scan protocol Array scanning was performed by using a ScanArray Lite (PerkinElmer Life Sciences) Laser Power= 75; PMT(Cy3)=85; PMT(Cy5)=80, resolution 5 µm/pixel.
Description TIFF images were analysed with TIGR Spotfinder v2.2.4. (from TIGR TM4 suite; Saeed et al., Biotechniques 34(2): 374-8. 2003) using Otsu thresholding with min SpotSize=10; maxSpotSize=55
Data processing Non linear LOWESS based lockfit alogorithm employing MIDAS (from TIGR TM4 suite; Saeed et al., 2003)
