为了提高免疫检测的速度 ,简化操作步骤 ,人们建立了一种新的检测技术———免疫层析技术。它利用纤维膜的毛细作用 ,使待测物 (抗原 /抗体 )沿膜表面向前运动 ,与检测区标记的捕获物特异结合而聚集显色。它既有免疫学方法的特异性 ,又有简便快速不须仪器的特点。本文介绍了它的方法学和应用 ,并对其将来的发展方向进行了探讨
In order to improve the speed of immunoassay and to simplify the operation steps, a new detection technique --- immunochromatography was established. It utilizes the capillary action of fiber membrane to make the analyte (antigen / antibody) move forward along the membrane surface and specifically bind with the capture of the labeled area in the detection area to aggregate and develop color. It has the specificity of immunological methods, but also simple and fast without the characteristics of the instrument. This article describes its methodology and application, and explores its future development
