(A) Analysis of homologous recombinant ES cell clones by Southern blot using an sγ1 probe. EcoRI digestion of genomic DNA yielded fragment sizes of 13.0 and 8.0 kb of the wild-type (+) and Ad-hMT (Ad) alleles, respectively. (B) Analysis of heterozygous and homozygous targeted mice and C57BL/6 wild-type littermates. Agarose gel electrophoresis of PCR products of tail DNA amplified with primers 1, 2, and 3.
