Intracellular expression of INF-γ on RAW264.7 macrophage cell. Flow cytometry analysis was used to assess the intracellular expression of INF-γ. The figures show the expression percent of INF-γ on RAW264.7 cell stimulated with (A) 1 μg/ml LPS alone as a control. (B) 1 μg/ml LPS + T. crispa 100 μg/ml. (C) LPS1μg/ml + T. crispa F2 100 μg/ml. The number was represented the mean percent of the cell ± SD. *Significant P ≤ 0.05 versus control.
