Southern blot hybridization results.

The genomic DNA extracted from six transgenic mice and one wild-type mouse was digested with EcoR I and Bgl II and hybridized using a DIGD-110-labeled probe. Lane 1 to lane 6, EcoR I- and Bgl II-digested DNA from six mouse tails (No. 9, No. 19, No. 20, No. 22, No. 24, and No. 31). Lane 7, genomic DNA fragments from the wild-type mouse as a negative control. Lane 8 to lane 9, PCR products of transgene LUM as positive controls.
