Fig. 2. Purification of DH31-like material from 150 R. prolixus
CNS through RPLC system A. The active fraction 28 was then run through system
B. Aliquots were tested by a DH31 ELISA to determine
DH31-like immunoreactive fractions. The elution times of
Drome-DH31 and Dippu-DH31 are indicated by the
asterisks.
