[Cloning and characterization of p43 cDNA from Trichinella spiralis].

Objective: To clone and characterize the p43 cDNA from muscle larvae cDNA library of Trichinella spiralis (Ts) Chinese isolate.

Methods: PCR technique was used to amplify the target cDNA from muscle larvae cDNA library. After cloned in pMD18T vector, it was transformed into E.
