Abstract
Based on the notion that regions of structural genes which encode critical domains of the corresponding proteins are highly conserved among closely related species, oligonucleotide primers were designed and used to amplify the α-globin sequence(s) of the Sprague-Dawley (SD) rat. Data of these amplified sequence constructs showed that two new rat a-globin specific sequences have been identified. Southern hybridization confirmed the presence of these sequences in the rat genome.
