D hemolymph (Table II). HP8 and PAP3 identified at 70 ?80 kDa may represent their catalytic domains in complex with serpin-6 (19). Since most serpin-HP complexes resided in gel slice-4 (70 ?80 kDa), we were unable to distinguish them or identify their components in this analysis. Serpin-9 displayed interesting changes: its level was higher in na e plasma and became lower after the challenge (Table
