Passive sensitization of mice and rats with IgE antibodies.

The strain-dependent variation in susceptibility to passive sensitization of the skin and peritoneal mast cells with homologous IgE antibodies was observed in inbred strains of mice. Strain 129 showed low susceptibility to passive sensitization and high efficiency of normal serum in blocking mouse reagin-induced PCA in rats. Balb/c and C3H/A strains showed… CONTINUE READING
