Abstract:
Affymetrix microarrays are widely used to measure the global expression of the mRNA transcripts of an organism’s genome. Affymetrix technology is based upon the concept of a /probe set/. All of the individual probes within a probe set are presumed to hybridize to the same unique mRNA transcript. However, the grouping of probes into probe sets is currently based on what the designers wish to measure not based on what they are actually measuring. In this talk I will discuss the bioinformatics resources developed to target the problem as well as challenges faced.
