Comparative analysis of the proteolytic profile of Ae. albopictus larvae from (A) eggs obtained from the natural environment in endemic regions of Rio de Janeiro and (B) eggs obtained from colonies maintained for a long time period. Proteolytic activities were detected after incubating the gels for 2 hours at 37°C in 0.1 M Tris–HCl buffer (pH 7.5). The numbers on the right indicate the apparent molecular masses of the peptidases (kDa).
