This track shows expression data from GNF (The Genomics Institute of the Novartis Research Foundation) using Affymetrix GeneChips. Chipset information is available using the Filter control.
For detailed information about the experiments, see Su et al., "Large-scale analysis of the human and mouse transcriptomes.", PNAS, Mar 19, 2002. Alignments displayed on the track correspond to the target sequences used by Affymetrix from which to choose probes.
In dense mode, the track color denotes the average signal over all experiments on a log base 2 scale. Lighter colors correspond to lower signals and darker colors correspond to higher signals. In full mode, the color of each item represents the log base 2 ratio of the signal of that particular experiment to the median signal of all experiments for that probe.
More information about individual probes and probe sets is available at Affymetrix's netaffx.com website.
The track filter, accessible via the gray bar at the left in the graphical display, can be used to change the display mode, group the displayed results, and change the display colors.
Thanks to GNF for providing these data.
