Objective:
To construct a cDNA library from Schistosoma japonicum cercariae.
Methods:
Total RNA was extracted from 500,000 S. japonicum cercariae and used to synthesize the double-stranded cDNA and cloned into the TriplEx2 vector using "SMART cDNA Construction Kit".
Results:
The primary titer of the constructed cDNA library is 1.8 x 10(7) pfu/ml and the titer of amplified library is 2.5 x 10(10) pfu/ml. The average size of inserts is 1.075 kb. The recombinant efficiency is 94.4%. The full length cDNA of S. japonicum TPI and JF-2 genes was successfully amplified from the library.
Conclusion:
A cDNA library of S. japonicum cercariae has been constructed successfully.
