(15) In this report, we employ a competition assay to confirm that this alloresponse involves a groove-binding peptide, demonstrate that this peptide derives from or depends on fetal calf serum and exploit a panel of antigen-presenting cell lines--each displaying an Ak complex with a different position 69 substitution--to establish that the alloresponse is not just a heteroclitic response to ribonuclease, itself.
(16) The results indicated temporal and individual variations in the titers of each class of Ab as well as the existence of enhancer and heteroclitic Ab.

(19) Heterocliticity towards non-human GH was also detected.
(20) Some of the antibodies could be inhibited to a greater degree with the cross-reacting haptens than with the haptens homologous to the immunizing antigen, therefore these antibodies were heteroclitic.
Locative
Definition:
(a.) Indicating place, or the place where, or wherein; as, a locative adjective; locative case of a noun.
