Identification of activation of B lymphocytes treated by FVPB2. (A) The activated B lymphocytes were identified with anti-CD19-PE and anti-CD25-APC. (B) Secretion of IgG and IgM by mouse spleen lymphocytes incubated with FVPB2. Mouse spleen lymphocytes were incubated with 200 μg/mL FVPB2, 10 μg/mL LPS or PBS. Each value represents the mean ± SD of separate triplicate experiments. Values were significantly higher than those of controls are indicated by *P <0.05 and **P <0.01).
