  • Study animals (amplification targeting) received unlabeled antibody 73 h earlier and unlabeled polymer 43 h earlier (Fig. 1). Control animals did not receive antibody.

  • * Student t test for significance, P < 0.05 (statistically significant values are underlined).

  • Data are expressed as average %ID/g ± SD; n = 4.
