A sensitive and convenient enzyme-linked immunosorbent assay method in serum MG7 antigen detection in gastric cancer

Objective To explore a highly sensitive and highly specific method to detect the serum MG7 antigen(Ag)level for early gastric cancer diagnosis.Methods The serum MG7-Ag level was detected by enzyme-linked immunosorbent assay(ELISA)method in 116 preoperative gastric cancer patients,63 postoperative gastric cancer patients,41 patients with precancerous lesion,37 pa-

软骨藻酸检测方法研究进展

综述了软骨藻酸的检测方法,包括酶联免疫吸附法、高效液相色谱法以及高效液相色谱-串联质谱法等方法的原理及优缺点,同时介绍了软骨藻酸在贝类、拟菱形藻、血液、尿液等样本的检测方法及其应用,生物传感器法、分子印迹法等新型技术也被用于软骨藻酸的检测,近年来长期慢性低剂量摄入软骨藻酸对生物体的影响受到广泛关注,可作为今后研究重点。
