This is identical to GPL1261 but a custom cdf environment was used to extract data. The custom CDF (Mm_Unigene_10) can be found at the Web link below and also as a supplementary file at the foot of the record.
CDF file was created by Microarray Lab at the Molecular and Behavioral Neuroscience Institute at the University of Michigan. After probe sequences are BLASTed against the latest UniGene Build and genome sequence, a series of filtering and grouping criteria are applied for different CDF files. A probe must hit only one genomic location. Probes that can be mapped to the same target sequence in the correct direction are grouped together in the same probe set; Each probe set must contain at least three oligonucleotide probes and probes in a set are ordered according to their location in the corresponding exon;
