Line Name DNA Construct
1. En-1 (hd) (+/-) For the targeting vector G, En-1 genomic sequences from the 129 mouse strain were used. The long arm consists of a 5.4 kb EcoRI-BglII genomic frag....
2. En-1 (hd) (-/-) For the targeting vector G, En-1 genomic sequences from the 129 mouse strain were used. The long arm consists of a 5.4 kb EcoRI-BglII genomic frag....
3. En-2 (hd) (-/-) The En-2 mutation created by homologous recombination resulted in the replacement of approximately 1-kb of the engrailed-2 En-2 gene, consisting of 300-bp of intron and....
4. En-2 (ntd) (-/-) An exon 1 En-2 (engrailed-2) targeting vector of the positive/negative type (Mansour et al., 1988; G00-372-934) was made from genomic DNA from C3H strain mice. The vect....
5. En-1 in Wnt-1(+/-) The neo cassette used was a modification of pMC1neopA (Thomas and Capecchi et al., 1987; G00-354-270). Initially, a neo-tk cassette was constructed by cloning a Bg....

7. En-1 in Wnt-1(-/-) The neo cassette used was a modification of pMC1neopA (Thomas and Capecchi et al., 1987; G00-354-270). Initially, a neo-tk cassette was constructed by cloning a Bg....
8. HNF-3beta (-/-) The HNF-3beta (hepatocyte nuclear factor-3beta) genomic clone used in this study was obtained from a 129/Sv mouse strain lambda-dash genomic library (gift of Andrew Reau....
