Abstract
This invention provides methods for producing antibodies, wherein the methods comprise the step of administering an immunogen comprising both a target antigen and a background antigen to transgenic animals, into which a gene coding for the background antigen has been introduced. Since immunotolerance to the background antigens have thus been induced in the transgenic animals, the animals efficiently produce antibodies to target antigens.
