Expressed sequence tags (ESTs) (1) are sequences of cDNA fragments prepared from different tissue sources. Each cDNA library is constructed from total RNA or poly (A) RNA derived from a specific tissue or cell, and thus the library represents genes expressed in the original cellular population. They represent a snapshot of genes expressed in a given tissue and/or at a specific developmental stage.
