Both the pre-fractionation sample or the filtrate fraction were diluted 20-fold with EMEM medium (final concentration about 0.6 mg / mL). As a control, PBS was diluted 20-fold with EMEM medium instead of the sample. Each sample (control, pre-fractionation, filtrate fraction) diluted with a medium was added to each dish group. After 24 hours of culture, lipopolysaccharide (LPS) was added to a final concentration of 1.0 ⁇ g / mL. The mixture was allowed to stand for 3 hours, RNA was collected, and cDNA was synthesized by reverse transcription. Next, EEF1A1 and IL-1 ⁇ were measured by RT-RCR.
