Also, the Honolulu technique will likely provide a highly reliable means for creating transgenic animals--ones capable of producing protein-based supplements and drugs. The biotechnology company ProBio America, Inc. has licensed the method for commercialization and is testing alternative uses. Some hope it may one day be used to preserve wild or endangered species. For now, only time and ethics can reveal the technique's limits.
