Production and characterization of monoclonal antibodies against the major cysteine proteinase of Trypanosoma cruzi

{{output}}
In the present study we describe the production and characterization of a panel of monoclonal antibodies (MoAbs) directed against cruzipain (Crz), the major cysteine proteinase from Trypanosoma cruzi. The five MoAbs, BD6, BF2, CG2, CH8, and DC10 were analysed with respect to affinity and specificity. None of the MoAbs cross-reacted with papain, which has regions of high homology with Crz. Treatment of the antigen with periodate did not affect the binding o... ...
