Inflammatory cytokine profiles were measured using a Human Inflammation Array C3 Kit (RayBiotech, Norcross, GA) according to the manufacturer’s protocol. Briefly, DPB-LPS (1 μg/ml) and/or EETC (10 mg/ml) was added in culture medium and harvested after 24 h treatment for conditioned medium (CM). Cytokine array membranes were blocked with blocking buffer and incubated with equal protein amounts of CM for 24 h. After extensive sequential washing with Buffer I and Buffer II, the membrane was reacted with a cocktail of biotin-conjugated antibodies against different individual cytokines. The membrane were washed again and reacted with horseradish peroxidase (HRP)-conjugated streptavidin. Relative protein expression was detected by the enhanced chemiluminescence (ECL) system. Densitometric values were quantified using TINA-program software.
