Jj. Heus et al., CENTROMERIC AND NONCENTROMERIC ADE2-SELECTABLE FRAGMENTATION VECTORS FOR YEAST ARTIFICIAL CHROMOSOMES IN AB1380, PCR methods and applications, 7(6), 1997, pp. 657-660
We have constructed a set of fragmentation vectors for the truncation
of either the centromeric or the noncentromeric end of YACs containing
a human DNA insert. These vectors carry ADE2 or HIS5 as the selectabl
e marker, enabling direct use in AB1380, the host strain of most publi
cly available YAC libraries. Centromeric fragmentation vectors for AB1
380 have not been reported previously; the noncentromeric vectors show
high frequencies of fragmentation.
