EST Library

**Semantic type:** Manufactured Object

**Definition:** A random cDNA library comprised of 200-800 bp random pooled mRNA clones isolated from a specific organism, specific tissue and/or a given stage of development. Clones are randomly selected for single-pass sequencing reads, the raw sequence reads are processed to remove low-quality sequence information and contaminating vector sequence and the resulting higher-quality sequences can be aggregated and aligned with others to assemble complete genetic or genomic sequences.

**Synonyms:** - Expressed Sequence Tag Library
