Selection of phage antibodies with GPX activity by combination of phage displayed antibody library with chemical modification and their characterization using a surface plasmon resonance biosensor.

谷胱甘肽过氧化物酶（GPX）是清除活性氧的重要抗氧化酶。为获得人源化GPX催化抗体，本研究以噬菌体展示人抗体库为材料，经多轮筛选获得新型抗体。以三种S-2,4-二硝基苯基谷胱甘肽酯半抗原GSH-S-DNP-Bu（B）、GSH-S-DNP-He（H）和GSH-S-DNP-cHe（C）为靶标，经ELISA四轮筛选，得到具有谷胱甘肽（GS...
