WebThe purity of protease was verified by SDS-PAGE as a single band at 35 kDa, which was confirmed as LasB elastase . Purified LasB exhibited an increase in elastase-specific activity ( Table 2 ). As shown previously on zymography ( Figure 3 ), Pa 2 exoproducts presented a clear band at 80 kDa, different from the rest. WebElastase is another protease that induces disintegration of the axoneme by microtubule sliding in the presence of ATP. Elastase and trypsin, both at μM levels, differ in their effects on the flagellar waveform of reactivated sperm [66,67], suggesting that they disrupt different structural components.
