Antibodies with fully human variable regions against a specific antigen can be prepared by administering the antigen to a transgenic animal which has been modified to produce such antibodies in response to antigenic challenge, but whose endogenous loci have been disabled. Various subsequent manipulations can be performed to obtain either antibodies per se or analogs thereof.

Los anticuerpos con regiones variables completamente humanas contra un antígeno específico pueden ser preparados administrando el antígeno a un animal transgenic que se ha modificado para producir tales anticuerpos en respuesta al desafío antigenic, pero que se han inhabilitado lugares geométricos endógenos. Las varias manipulaciones subsecuentes se pueden realizar para obtener los anticuerpos por sí mismo o los análogos de eso.
