Figure 4. In vitro sporozoite invasion of DF-1 cells transiently transfected with EtAMA1. (a) Verification of pcDNA3.1-(+)-EtAMA1 expression in DF-1 cells by IFA. (b) The proliferation of DF-1 cells transfected with pcDNA3.1-(+)-EtAMA1 or pcDNA3.1-(+). (c) Sporozoite invasion rate in DF-1 cells transfected with pcDNA3.1-(+)-EtAMA1 or pcDNA3.1-(+). *p <0.05 and **p <0.01, as determined by the Student's t-test versus the untreated group.
