摘要:
Porcine animals, tissue and organs as well as cells and cell lines derived from such animals are provided that lack functional endogenous immunoglobulin loci and are deficient in immunoglobulin expression and B-cells. These animals are useful as model systems for research and for development of new pharmaceutical and biological agents. In addition, methods are provided to prepare such animals.
