kidney
is an exprSet containing the data from 1 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.
The chip was produced in 2001 by Holger Sueltmann at the Division of Molecular Genome Analysis at the German Cancer Research Center in Heidelberg.
