sds-page protein pattern and its antigenicity analysis of different isolates of schistosoma japonicum in china. | homogenates prepared from s. japonicum adult worms of different isolates from anhui, hubei, guangxi, yunnan and sichuan provinces were analyzed by sds-page and enzyme linked immunoelectrotransfer blot (eitb) tested with rabbit anti-snails antibody. the results of sds-page indicated that with silver staining both male and female worms of guangxi isolate showed some definite differences in their protein profile, namely, absence of one band between 50-75 kda in male worms and marked reduction in qu ... | 1994 | 8187569 |
variation in the sequence of a mitochondrial nadh dehydrogenase i gene fragment among six natural populations of schistosoma japonicum from china. | the present study investigated the level of genetic variation among schistosoma japonicum populations of different geographical origins from mainland china. polymerase chain reaction-based methods were employed to determine the sequence for a subunit of the mitochondrial nadh dehydrogenase i gene for populations from zhejiang, anhui, jiangxi, hunan, hubei and sichuan. no variation was detectable in the nadh dehydrogenase i sequence within populations from zhejiang and hubei, whereas sequence var ... | 1998 | 9925274 |
