Figure 2
The levels of immunoglobulin (Ig)G secreted into the gastric lumen as determined by expression of neonatal Fc receptors for IgG (FcRn) in the stomach. Six hours after intravenous (IV) injection of rabbit IgG or phosphate-buffered saline (PBS) as a vehicle control into FcRn+/+ and FcRn−/− mice (each n=5), the levels of rabbit IgG in the gastric secretion of the mice were measured by enzyme-linked immunosorbent assay. Data are represented as mean±s.e. (n=5). *P<0.05 according to Student's t-test.
