Anti-Bermuda grass RAST binding is minimally inhibited by pollen extracts from ten other grasses.

This article addresses the question, Does sensitization with Bermuda grass pollen generate IgE antibodies that cross-react with other grasses? We found that none of ten non-Bermuda grass extracts attained 50% inhibition of RAST binding between sera from patients in Arizona and Bermuda-coupled disks whereas Giant Bermuda grass extract was completely cross-reactive with Common Bermuda grass.
