Intensity data for 8 cDNA slides with CLL and DLBL samples from the Alizadeh et al. paper in Nature 2000
8 cDNA chips from Alizadeh lymphoma paper
lymphoma is an
containing the data from 8 chips
from the lymphoma data set by Alizadeh et al. (see references). Each
chip represents two samples: on color channel 1 (CH1, Cy3, green) the
common reference sample, and on color channel 2 (CH2, Cy5, red) the
various disease samples. See
pData(lymphoma). The 9216x16
exprs(lymphoma) contains the background-subtracted spot
intensities (CH1I-CH1B and CH2I-CH2B, respectively).
The chip intensity files were downloaded from the Stanford microarray database. Starting from the link below, this was done by following the links Published Data -> Alizadeh AA, et al. (2000) Nature 403(6769):503-11 -> Data in SMD -> Display Data, and selecting the following 8 slides:
Then, the script
makedata.R from the
of this package was run to generate the R data object.
