常用的免疫荧光反应(IFA)虽有高度的敏感性和特异性,但其弱点是在免疫复合物中由紫外光激发出的荧光很易衰变,因而制备的标本片需即时观察,不能保存,给教学、科研和摄影工作带来诸多不便。为了能较长时间保存荧光标本片,使其在紫外光的照射
Although the commonly used immunofluorescence reaction (IFA) is highly sensitive and specific, its weakness is that the fluorescence excited by ultraviolet light in the immune complex is easily decayed, and thus the prepared specimen needs to be observed immediately and can not be preserved. To teaching, research and photography work a lot of inconvenience. In order to be able to save a long time fluorescent specimens, make it in the ultraviolet light irradiation
