Fig 8. Proliferative activity of peripheral blood leukocytes (PBL) from vaccinated fish in response to antigen stimulation.

Fig 8

PBL from turbot vaccinated with pCN247, pCN523, or pCN3 were treated with or without (control) rP247, rP523, or ConA, and cellular proliferation was determined by MTT assay. Stimulation index was defined as fold increase in the proliferation of antigen-treated cells compared to that of the untreated control cells. Data are presented as means ± SE (N = 3). N, the number of times the experiment was performed. **P < 0.01.
