title: The kinetic behaviour of radiolabelled IgG1 derived from different sources in adult sheep and neonatal lambs.
abstract: The turnover rate and pool volume of radiolabelled autologous IgG1 was similar to homologous IgG1 in adult sheep. In neonatal lambs there was no significant difference for either of these parameters between homologous serum IgG1 and maternal colostrum IgG1. However, the pool volume for IgG1 expanded by approx. 30% over the experimental period in the lambs. When the turnover rates were corrected for this increase they were found to be similar to those observed for IgG1 in adult animals.
