Conclusion
SAGE is a well-recognized method of gene-expression profiling. The information gathered from SAGE analysis enables a clear view of the genes associated with normal, developmental, and disease states. Researchers require an efficient means of accessing the sequence information contained in the concatamer of transcript tags. ABI PRISM 3100 and 3700 DNA sequencers, coupled with BigDye terminator chemistry, provide a versatile approach to generating ditag sequences, and make the SAGE application readily accessible to disease investigators.
