abstract：:The human beta-globin LCR plays a key role in the transcriptional regulation of the beta-globin locus and comprises four erythroid specific DNase I hypersensitive sites, designated 5'HS1-4. We have now isolated genomic clones containing 5'HS3 and 5'HS4 of the mouse beta-globin LCR. 5'HS3 and 5'HS4 are located 15 kb an...
