olineu with Y27631 treatment
|
| Organism |
Mus musculus |
| Characteristics |
Cell lysates from Olineu Y27631 treated

| Hybridization protocol |
- hybridization according to Agilent 60-mer oligo microarray processing protocol v2.1 with the following modifications:
2 micro gram labeled DNA per channel were mixed
no fractionation
probes were denatured for 3 min at 98 degree celsius
hybridization at 63 degree celsius
SSPE washes as recommended
slides were dipped in acetonitril (10 s) then dried
|
| Scan protocol |
- scanned with a G2505B Microarray Scanner (Agilent Technologies)
- quantification software: 'Automic Imageprocessing for Microarrays'

|
| Description |
- RNA quality control with Agilent Bioanalyzer 2100
- Dye incorporation with NanoDrop ND-1000
Keywords = oli neu, oligodendrocyte differentiation
|
| Data processing |
- dye swap design
- Normalization of the log2(cy3/cy5)-ratios with pinwise non-linear loess regression
- variance homogenisation by division of each value with the standard deviation of the normalized log2-ratios
- as statistical software we use 'R'
