Figure 1.

Total ΔSFC per million cells detected in response to stimulation with (a) Omp25 antigen or (b) IalB antigen, for each of the vaccine groups. Measured from splenocytes harvested at three weeks post-vaccination. (a) stimulation of splenocytes with Omp25 antigen (10 ug/ml). (b) Stimulation of splenocytes with IalB antigen (15 ug/ml). Bars represent the total ΔSFC detected per million splenocytes for each vaccine (Number of spots detected in stimulated sample - number detected in corresponding unstimulated sample). Error bars represent the standard deviation of replicate samples.
