The fate of protein antigen in earthworms: study in vivo.

abstract：:H-2-linked gene(s) have been found to play a role in the quantitative regulation of response to human gamma-globulin (HGG) in mice selected for high or low antibody responsiveness to sheep erythrocytes. Unexpectedly, in a random genetically heterogeneous population of F2 interline hybrids, the gene(s) linked to the H-...
