Figure S1. Anti-inflammatory activity. The levels of IFN- γ and TNF- α were determined by a sandwich ELISA test in J774 cells untreated; J774 cells infected with S. epidermidis for 1 h; J774 cells stimulated with RJI-C (9 μg/ml) for1 h; J774 cells stimulated with TB-KK. (6 μg/ml) for1 h; J774 cells stimulated with MIX (RJI-C 9 μg/ml + TB-KK 6 μg/ml) for1 h; J774 cells infected with S. epidermidis for 1 h and stimulated with MIX for 1 h. Results from two representative experiments are presented as mean value ± S.D. *P <0.05, **p < 0.01; ***p < 0.001, Student’s t test S. epidermidis vs S. epidermidis + MIX.
