title: Two-dimensional gel electrophoretic analysis of the HindIII 1.8-kb repetitive-sequence family in the human genome.
abstract: The structure and organization of a human repetitive DNA family containing the HindIII 1.8-kb repetitive sequence were studied, using two-dimensional (2D) gel electrophoresis. The HindIII 1.8-kb sequence proved to be part of a repetitive sequence about 5 kb long and interspersed on the genome. The long repetitive sequence family contained several subgroups, as based on polymorphism of the restriction site. Recombinant phages containing the long repetitive sequence were isolated from the human genomic DNA library. Heteroduplex and restriction analysis showed that the structure of the repetitive sequence carried by the phages was close to that expected from 2D gel electrophoretic analysis. The 2D gel electrophoretic analysis was shown to be a reliable and useful approach for surveying and mass analysis of repetitive sequence families.
