Objective To improve Western blotting to detect specific IgG antibodies against the large hydrophilic domain(HD)of the 23-ku membrane protein of Schistosoma japonicum(Sj23HD)to monitor early schistosomiasis in sentinel mice and to determine the value of its actual use. Methods NC membranes with the Sj23HD protein attached were prepared ahead of time and chemiluminescence was used to detect specific IgG antibodies against Sj23HD antigen in sera from sentinel mice.The consistency and sensitivity of this Weste...
