To All, I'm working on a term paper on DNA chips, particularly a hypothetical application for a colorectal cancer probe array. I've been using AFFX as a reference. Does anyone know the answer or could point me to an article or reference for the following questions: 1) Are the current DNA chips sensitive enough to probe source material without needing (PCR) amplification? (From old articles I've read earlier chips needed PCR. Would future chips be sensitive enough?) 2) Is a colorectal cancer genetic test an appropriate use for DNA chips? Thanks in advance for any help. (Apologies if this isn't the correct place to post.) -- Doug Neubauer
