Validating METCAM/MUC18 as a Novel Biomarker to Predict the Malignant Potential of Prostate Cancer at an Early Stage by Using a Modified Gold Nanoparticles-Based Lateral Flow Immunoassay.

为进一步验证METCAM/MUC18作为前列腺癌诊断生物标志物，作者利用生物素与链霉亲和素的极高亲和力，设计了改良侧流免疫层析（LFIA）以提高灵敏度和特异性。方法上，将商品化生物素化兔抗体（EPP11278）或自制生物素化鸡抗体，与金纳米颗粒偶联的自制鸡抗体或商品化兔抗体（EPP11278）组合，用于改良LFIA；以两种重组MET...
