Abstract: In recent years, bacterial artificial chromosome (BAC) library has become one of the most popular used genome library, and it is used generally in the research of eukaryotic organism that has longer genome by its advancement including larger capacity, stable inherited characteristic, few chimera, easily reclaiming insertion element, convenient operation and so on. This article researched the constructing condition of BAC library, cutting the goat’s chromosome by HindⅢ enzyme, separating the big DNA fragment by pulsed field gel electrophoresis, reclaiming DNA by electrodialysis, linking with BAC bearer taken off phosphorous, transforming competent cell DH10B by elutriations, and finally evaluating the length of fragment by cutting the DNA with NotⅠenzyme. The consequence indicated that the method that this research chose can get not only the longer insertion element, but also the higher converting efficiency, and it is the better method to construct the bigger genome BAC library.
