| Abstract: | Expressed sequence tags (ESTs) provide useful molecular landmarks for physical mapping and identify the position of an expressed region in the genome. The use of subtracted cDNA libraries enriched for tissue-specific genes as a source of ESTs should reduce the repetitive isolation of constitutively expressed sequences. We report here the sequence tags from the 3'-end region of 58 new directionally cloned cDNAs from a subtracted human retinal pigment epithelium (RPE) cell line library. Eight of the cDNAs have been assigned to human chromosomes using PCR-based EST assays. Chromosomal mapping of subtracted RPE cDNA clones may also help in identifying candidate genes for inherited eye diseases. |
