EST (expressed sequence tag): A unique stretch of DNA within a coding region of a gene that is useful for identifying full-length genes and serves as a landmark for mapping. An EST is a sequence tagged site (STS) derived from cDNA.
An STS is a short segment of DNA which occurs but once in the genome and whose location and base sequence are known. STSs are detectable by the polymerase chain reaction (PCR), are helpful in localizing and orienting mapping and sequence data, and serve as landmarks in the physical map of the genome.
An Expressed Sequence Tag is a tiny portion of an entire gene ... used to generate what are called Expressed Sequence Tags, or ESTs.
The Expressed Sequence Tags database contains sequence data and other information on single-pass cDNA sequences and is a division of GenBank.
An expressed sequence tag or EST is a short sub-sequence of a cDNA sequence. They may be used to identify gene transcripts, and are instrumental in gene discovery and gene ...

ABSTRACT: Expressed Sequence Tags or ESTs provide researchers with a quick and inexpensive route for discovering new genes, for obtaining data on gene expression and ...
