Abstract: In order to obtain the purified SV40-large T antigen (SV40-LT) and its specific antibodies, the high antigen index region of SV40-LT antigen was overexpressed in DE3 cells firstly, and then the purified LT antigen was vaccinated into rabbit, and induced specific antibody against SV40-LT. The results of western blot and ELISA showed that the expression products not only had well immunogenicity, but also could induce rabbit to produce higher levels of antibodies (antibody titre 1∶6400).

Key words: SV40-LT gene, prokaryotic expression, antibody, ELISA
