This data set was searched against the M. musculus proteome on March 21st, 2006. It was anonymously donated the the GPMDB. The data can be found here.
The unusually large signals from lysosome-specific proteins suggest the sample was prepared by centrifugation, with mitochondrial and microsomal contaminants. Of the top ten proteins listed (excluding albumin), all are the best exemplars for those proteins in GPMDB (as of 12/29/2007).
