|
| Extracted molecule |
total RNA |
| Extraction protocol |
On average, 30 ug of tissue was homogenized in trizol buffer, and RNA extraction was performed according to maunfacturer's instructions.
|
| Label |
biotin
|
| Label protocol |
Refer to Liu et al (PNAS 101: 9740-9744 (2004)). 5 ug of total RNA was labeled in reverse transcription at 37C for 90 mins by using biotin-labeled rand-octomer oligo primer. The RT reaction mix was further denatured by using 0.5 N NaOH / 1 mM EDTA at 65C for 15 mins and neutralized by 1 M Tris HCl pH 7.6. Biotin signal was detected with an Alexa 647-Streptavidin conjugate.

| Hybridization protocol |
The chips were hybridized on Tecan HS 4800 hybridization station. Chips were pre-hybridized at 25C for 30 min in the buffer of 6x SSPE/ 30% formamide/ 1x Denhardt's solution. The chips were further hybridized with labeled target in 6x SSPE/ 30% formamide at 25C for 18 hr. Hybridization, post-hybridization washing in 0.75x TNT (Tris, sodium, Tween 20) (see PNAS) at 37C for 40 mins. The chips were stained by streptavidin-alexa647 (1:500) dilution in TNT for 30 mins. Post-staining washing in 1x TNT FOR 40 min. Rinse with water and spin dry.
|
| Scan protocol |
Arrays were scanned on the GenePix scanner and analyzed using the GenePix Pro software package.
|
| Data processing |
Raw data were normalized by the print-tip loess method (Hua YJ, Genomics 2008)
