To construct intestine specific
cav-2 clones, we used Gateway multisite technology (Invitrogen, Paisley, UK). Individual entry clones containing the
vha-6 promoter and
cav-2 cDNA were produced and then combined in a Gateway reaction into the destination vector pHP2 (H. Peterkin and H. Baylis, unpublished data). The
vha-6 promoter clone contained a fragment, similar to that previously used by Grant and colleagues (Chen et al., 2006), amplified using the oligonucleotides ggggacaagtttgtacaaaaaagcaggctcgcgttcaccactcgaccaccgaac and ggggacaacttttgtatacaaagttgttttttatgggttttggtaggttttag. The
cav-2 cDNA was amplified using the oligonucleotides ggggacaacttttctatacaaagttgaaaaatgactcgtcagaatacttccgaaag and ggggacaactttattatacaaagttgttaaacatgatgaatgtgtttttc.
