abstract：:Site-specific recombination provides a powerful tool for studying gene function at predetermined chromosomal sites. Here we describe the use of a blasticidin resistance system to select for recombination in mammalian cells using the yeast enzyme FLP. The vector is designed so that site-specific recombination reconstru...
