Example Sentences:
(1) Evidence is presented that the type-specific antibody to the adenovirus hexon is not simply the antibody with the highest activity for cross-reactive determinants, but is a distinct, minority population that recognizes seperate determinants.
(2) We have tested the two principal theories which explain the previous finding that small amounts of type-specific antibody to the adenovirus hexon can neutralize infectivity, whereas even large amounts of cross-reactive antibody do not.
