Southern blot analysis of a Saoe-DRB11*0102 intron 1 clone. The clone was digested with different pairs of restriction enzymes. The digests were separated by gel electrophoresis, blotted, and the blot hybridized with an Alu-specific probe. (Lanes 1–3) Digests obtained after treatment with theBamHI/HindIII, HindIII/HincII, andBamHI/EcoRI enzymes, respectively.(Lane 4) Positive control. A 1.2-kb fragment containing Alu50J was amplified from human genomic DNA and blotted.
