Abstract
Summary
Benzylpenicilloyl (BPO) haptens of widely different molecular size were compared for their efficiency in eliciting PCA reactions in guinea pigs sensitized with rabbit anti-BPO antibodies. Equimolar doses of different sized haptens were found to be equipotent in eliciting the PCA reactions. Therefore, in this system the elicitation of PCA reactions by multivalent haptens could also be compatible with a simple bridging hypothesis.
