## Intensity data for one cDNA slide with two adjacent tissue samples from a nephrectomy (kidney)

### Description

Intensity data for one cDNA slide with two adjacent tissue samples from a nephrectomy (kidney)

### Usage

    data(kidney)

### Format

`kidney` is an `ExpressionSet` containing the data from one cDNA chip. The 8704x2 matrix `exprs(kidney)` contains the spot intensities for the red (635 nm) and green color channels (532 nm) respectively. For each spot, a background estimate from a surrounding region was subtracted.

### Details

The chip was produced in 2001 by Holger Sueltmann at the Division of Molecular Genome Analysis at the German Cancer Research Center in Heidelberg.
