SAGE database

Building up expertise in this field, EMBL with its data library is well positioned to play an important European role in estabfishing a reference DNA array and SAGE database. In the future, the micro-array technology will be developed also for proteins, applying miniaturization, nanotechnology, micro-fabricated devices and reaction chambers. 

Compositional analysis data for herbs are also limited however, these plants may be rich sources of flavones. For example, parsley is the major source of apigenin (217.9 mg/100 g) in the whole database, while sage and thyme are rich in luteolin (33.4 and 39.5 mg/100 g, respectively). 

Figure 16.1. Serial Analysis of Gene Expression (SAGE) depends on the generation of a tag from the 3 end of an mRNA, Tags are concatemerized and sequenced. These data are compared with a database of tags linked to individual transcriptsto generate the frequency of each tag in the library, a measure of the expression level for that gene. (See color plate.)...

Figure 16.6. The complete list of tags from the virtual Northern results (Figs. 16.4 and 16.5) can also be used to query the database, finding the occurrence of their tags in all SAGE libraries.
