摘要

Due to the size of bacterial artificial chromosomes (BAC), P1 artificial chromosomes (PAC) and P1 clones, it is often difficult to construct detailed restriction maps, with large number of restriction fragments leading to ambiguity of mapping data.Cre recombinase was used to linearize and asymmetrically introduce label at the unique loxP site of large loxP-containing clones. Subsequent partial digestion allows the direct ordering of restriction fragments. Additionally, BAC DNA linearized using theCre-lox system has been used successfully to generate transgenic animals.
