Sample GSM568439 Query DataSets for GSM568439
Status Public on Jan 01, 2011
Title JR32 infection of THP-1 macrophage time 18h (SCOTS treated), replicate 2
Sample type mixed
 
Channel 1
Source name 3XSCOTS cDNA obtained from JR32 infecting THP-1 macrophages at time 18
Organism Legionella pneumophila subsp. pneumophila str. Philadelphia 1
Characteristics condition: L pneumophila inside human THP-1 macrophages
Extracted molecule total RNA
Extraction protocol TRIzol reagent (Gibco BRL) was used according to the manufacturer instruction. RNA was treated with DNase I (Ambion). RNA sample was converted to cDNA in 5 independent reverse-transcription reactions as described previously (Graham, J. 1999. PNAS 96:11554-559). Bacterial transcript were purified from host transcript by using 3 rounds of the SCOTS procedure (Daigle, F. 2002. Methods Enzymol. 358:108-122).
Label AlexaFluor 546
Label protocol 2 µg of cDNA was labeled using amino-allyl dUTP (GE Healthcare) by random priming with Klenow (New England Biolabs) as previously described (Porwollik, S. 2001. Mutat Res 483:1-11.). Subsequently, the resulting cDNA was coupled to the succinimidyl ester fluorescent dye AlexaFluor 546.
 
Channel 2
Source name Genomic DNA used as reference channel
Organism Legionella pneumophila subsp. pneumophila str. Philadelphia 1
Characteristics reference: genomic DNA
Extracted molecule genomic DNA
Extraction protocol Wizard Genomic Purification Kit (Promega).
Label AlexaFluor 647
Label protocol 5 ug of genomic DNA was labeled with amino-allyl dUTP with klenow fragment and random hexamer as previously described (Porwollik, S. 2001. Mutat Res 483:1). Subsequently, the resulting DNA was coupled to the succinimidyl ester fluorescent dye AlexaFluor 647.
 
 
Hybridization protocol Hybridization was performed as previously described (Hovel-Miner, G 2009. JB, 191:2461).
Scan protocol Scanning and image acquisition was performed on a Scan Array Express (Perkin Elmer) using ScanArray 3.0 software as previously described (Hovel-Miner, G 2009. JB, 191:2461).
Description L. pneumophila infection of human macrophages (THP-1) at time 18h.
Data processing The data was background subtracted and normalized by calculating the contribution of each spot to the total intensity and the ratio to gDNA was recorded.
