What's the best source for information about specific genes?

We are interested in studying gene expressions in living animals, by means of different in-vivo and in-vitro imaging techniques. We also plan to execute tests on living organisms by using Affymetrix or Navigenics or equivalent DNA microarray test chips, but we know that interpretation of such tests are closely related to the ability to execute reliable and effective reannotation vs. existing validated databases of identified genes.If you want to know more fully soon visit our site best source of information!.  We know that services provided by Affymetrix often provide little informative annotation for most known genes (identified as "transcribed locus"), and we would like to know if anyone in the world can provide an effective reannotation service using our DNA microarray test files, i.e. by executing rigorous tests of our Affymetrix chip probeset sequences against all currently available transcript sequences in latest database releases.
