Extended Data Fig. 4 | Relative concentrations of all subclasses of IgG
between dams and pups. a–e, Serum IgG subclass concentrations in
μMT−/−FcRn+/+ (or FcRn+/−) and μMT−/−FcRn−/− pups fostered by μMT+/− dams for
1 week. f–j, Relative concentrations of all subclasses of IgG between dam and
pups. k, Adult (8-week-old) mice were orally gavaged with 5 mg of IgG, and
serum IgG concentrations were quantified as ng ml−1. NS, no significant
difference; calculated using a Mann–Whitney U-test. Specific n numbers are
shown in the figure.
