This track displays human tissue microarray data using
Affymetrix Human Exon 1.0 GeneChip.
The track was produced as part of the ENCODE Project.
This is release 2 of this track. This release includes 28 new cell types, and replaces the data for four existing tables (replicate 1 for K562, NB4, and SKMC; replicate 2 for HeLa-S3).
Display Conventions and Configuration
The display for this track shows probe location and signal value
as grayscale-colored items where higher
signal values correspond to darker-colored blocks. Items with score of 1000
are in the highest 10% quantile for signal value of that particular cell type.
Similarly, items scoring 900 are the next 10% quantile and at the bottom of
scale, items scoring 100 are in the lowest 10% quantile for signal value.
The subtracks within this composite annotation track correspond to data from
different cell types and tissues. The configuration options are
shown at the top of the track description page, followed by a list of
To display only selected subtracks, uncheck the boxes next to the tracks you
wish to hide.

Affy Exon Probes track, which can be found inside the
Affy Exon supertrack in the "Expression" track group.
Cells were grown according to the approved
ENCODE cell culture protocols.
A subset of the cells was stored frozen in RNALater. Total RNA was labeled and
hybridized to Affymetrix Human Exon 1.0 ST arrays. Exon and gene level
expression analysis were carried out using Affymetrix ExACT 1.2.1 and Affymetrix
Expression Console 1.1 software tools. Samples were quantile normalized for
background correction and Probe Logarithmic Intensity Error summarized.
