A cell-based ELISA assay kit (Abnova, Taoyuan, Taiwan, China) was used to measure the ERK1/2 phosphorylation level in Caco-2 cells. Caco-2 cells cultured in 96-well black side plates were used to perform ELISA according to manufacturer’s instructions. Fluorescence intensity was measured at 535/590 nm for ERK1/2 and 360/450 nm for total proteins using a microplate spectrophotometer to assess the normalized ERK1/2 phosphorylation level.
