A new fluorescent probe with high selectivity and sensitivity for Cys detection in bovine serum

]chromen-8-yl acrylate, BTAB) for Cys detection was synthesized with acrylic ester as the reaction site. Under the conditions of gradual optimization, BTAB can achieve selectivity and anti-interference ability for Cys detection. The linear range of Cys was 0.3-10 μM, and the detection limit was 0.154 μM. Finally, this probe was applied to detect the Cys content in bovine serum samples with satisfactory results.
