immune system
• mice have 80-100% the number of B cells as wild-type mice
• unimmunized mice produce significant levels of human IgM and IgG2
• IgM levels in sera ranged from 27.3-109.4 micrograms/ml
• IgG2 levels in sera ranged from 37.6-665.3 micrograms/ml
• immunizing mice with human antigens leads to production of antigen-specific antibodies with human sequences
