| Hybridization protocol |
Prior to hybridization, the test and reference probes were combined with 100 ug mouse fluorimetric Cot-1 (Invitrogen) and ethanol precipitated. Following centrifugation, the probes were resuspended in 110ul SlideHyb Buffer #3 (Ambion) containing 5ul of 100µg/ul Yeast tRNA (Invitrogen), heated to 95ºC for 5 minutes and incubated for 30 minutes at 37ºC to block repetitive elements on the probe. Hybridization was performed for 16 hours at 55ºC using a GeneMachine hybridization station (Genomic Solutions, Inc.) as described (Cowell, J. K. and N. J. Nowak. 2003. High-resolution analysis of genetic events in cancer cells using bacterial artificial chromosome arrays and comparative genome hybridization. Adv Cancer Res 90:91-125). After hybridization, the slides were automatically washed in the GeneMachines station with reducing concentrations of SSC and SDS. The final wash was 30 seconds in 0.1X SSC, followed by a two second 100 % ethanol dip. The slides were spun dry and scanned immediately at 5µm resolution using a GenePix 4000B laser scanner (Axon Inc.)
|
| Scan protocol |
Slides were scanned on a GenePix 4000B laser Scanner (Axon Inc.) using GenePix Pro V6.0/1. Both lasers were set to 100% and the PMT was set to 500 for cy3 and 450 for cy5
|
| Description |
tissue from mouse brain with high grade glioma.
|
| Data processing |
Images were analyzed using Imagene 6.0 (BioDiscovery Inc.). The output of Image analysis was further processed by in-house developed programs. The log2 ratios of the test/control (values are not background subtracted) were normalized using a subgrid loess, with all flagged spots and clones on the sex chromosome are given a weight of zero. The mean of the replicate measures was taken and the final normalized log2 ratio was plotted against its genomic location.
