| Title |
2h post-infection of THP-1 treated with 3 rounds of SCOTS, replicate 6 |
| Sample type |
mixed |
| |
|
| Channel 1 |
| Source Name |
3XSCOTS cDNA obtained 2h post-infection
|
| Organism(s) |
Salmonella typhi |
| Characteristics |
Salmonella typhi infection of THP-1 cells, recovered 2 h post-infection
|
| Treatment protocol |
2E7 THP-1 cells (treated with 1E-7 M phorbol 12-myristate 13-acetate) were infected with Salmonella typhi at a multiplicity of infection of 10:1. At time 0, cells were washed with PBS and fresh RPMI containing 100 ug ml-1 was added to the wells. After 2 hours, cells were washed with PBS and recovered in 5 ml PBS. After centrifuation, the pellet was lysed with 2 ml TRIzol (Invitrogen).
|
| Extracted molecule |
total RNA |
| Extraction protocol |
TRIzol reagent (Gibco BRL) was used according to the manufacturer instruction. RNA was treated with DNase (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 round of the SCOTS procedure (Daigle, F. 2002. Methods Enzymol. 358:108-122).

| Label |
Cy5
|
| Label protocol |
1.5 µg of cDNA was labeled with Cy5-dCTP (GE Healthcare) by random priming with Klenow (New England Biolabs) as previously described (Porwollik, S. 2001. Mutat Res 483:1-11.).

|
| Channel 2 |
| Source Name |
Reference genomic DNA
|
| Organism(s) |
Salmonella typhi |
| Characteristics |
Genomic DNA from Salmonella typhi ISP1820
|
| Growth protocol |
Salmonella typhi from overnight culture in LB broth.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Genomic DNA was extracted by standard phenol-chloroform method (Sambrook, J, Molecular Cloning, 3rd Edition)
|
| Label |
Cy3
|
| Label protocol |
1.5 µg of genomic DNA was labeled with Cy3-dCTP (GE Healthcare) by random priming with Klenow (New England Biolabs) as previously described (Porwollik, S. 2001. Mutat Res 483:1-11.).
|
| |
|
| |
| Hybridization protocol |
Samples we hybridized as previously described (Porwolik, S. 2003.Nucleic Acids Res 31:1869-76)
|
| Scan protocol |
Slide was scanned with Scan Array Lite (Perkin-Elmer) using Scan Array Express 2.1 software.
|
| Description |
This sample was used to analyse the effect of SCOTS on transcript population and to analyse the expression profiles of Salmonella typhi during infection of human macrophages (THP-1)
|
| Data processing |
After backgroud correction and total intensity normalization, ratio to reference were calculated and log base 2 transformed.
