[BioC] tissue contamination problem in microarray

[Hao Liu]

Dear All:

I would like to know if there are techniques to minimize the perturbation
caused by tissue contamination, for example, normal lung tissue
contamination on a breast metastasis. What is the best strategy to deal
with this problem? 

I think this should be dealt with at the "low" level normalization
process, please help.

Best regards
