Abstract excerpt
We introduced two mutant genes (beige or bg, which induces a deficiency of natural killer activity, and xid, which decreases the production of immunoglobulins) into KSN nude mice with high reproductive performance. At first we produced the KSN-bg/bg(nu/nu) (KSN-bg) and KSN-xid/xid(nu/nu) (KSN-xid) congenic strain by backcross (cross-intercross method). After we identified homozygosity at the biochemical locus and...
