Activation of B cells isolated from mouse spleen lymphocytes treated by FVPB2. (A) Expression level of CD19 and CD25 on purified B cells, which were treated by 200 μg/mL FVPB2, 10 μg/mL LPS, or PBS for 48 h as analyzed by FACS. (B) Secretion of IgG and IgM by purified B cells treated with FVPB2. Purified B cells were incubated with 200 μg/mL FVPB2, 10 μg/mL LPS or PBS as control. Each value represents the mean ± SD of separate triplicate experiments. Values significantly higher than those of the controls are indicated by *P < 0.05 and **P < 0.01).
