The first assigned mRNA/gene that is listed in the annotation file for a given probe set or transcript cluster is considered the "best" assignment based on data source quality ranking and assignment scoring system. To get a single best mRNA/gene assignment you can simply take the first one in the list in the annotation file.
Sometimes, there might be multiple best hits between transcript clusters (or probe set) and a mRNA/gene, with identical score and data source quality. In that case, the transcript assignments are ranked based on their descriptions (e.g., title from the GenBank record).
For transcript clusters that detect genes that are alternatively spliced, the different spliced forms will be ranked by length with the longest ones listed first.

The hyb/wash/stain kit for the GeneChip miRNA 3.1 Array Strips is different than that for the 3' IVT arrays and GeneChip ST array strips. Additional wash A steps have been added to ensure adequate washing after the array strips have been stained.

The suffixes, at the end of each probeset in GeneChip 3' IVT arrays, indicate what is known about the sequence at the time of design:
_at = all the probes hit one known transcript
_a = all probes in the set hit alternate transcripts from the same gene
_s = all probes in the set hit transcripts from the different genes
_x = some probes hit transcripts from different genes

Yes, but we recommend storing your GeneChip 3' IVT Array after hybridization and prior to the fluidics step, for no longer than 3 hours at 4 degrees C. Please remove the hybridization cocktail and fill with wash A before storing.
