Fig. 6. Serum IgG1 levels in vaccinated hamsters.
Total serum IgG1 levels against rOv-TSP-2-LAP were determined by indirect ELISA at pre-immunization, post-immunization and post-challenge infection. Results represent the mean absorbance measured at 450 nm. Each bar represents mean ± SD of each group. * P < 0.05, ** P < 0.01.
