64171 SAGE tags from the 5 week frontal nasal prominence (source R) library were sequenced. Of the 20503 different tags represented, 15549 match at least one gene or EST in the SAGEmap reference lists. 13880 tags appeared once with the most common tag appearing 641 times. The following links are entry points to the 54 pages covering the total of 27297 entries. The tags are listed in tables, ordered by the number of times each was sequenced. Tags with more than one database hit appear more than once. Each table record links the tag to its respective NCBI SAGEmap entry, UniGene_ID to a specific SAGEmap UniGene search, and the gene symbol to a LocusLink Query. Each page has approximately 500 tags listed.
