style=";font-family:宋体">精斑（</span>PSA<span style=";font-family:宋体">）试纸基于胶体金免疫层析技术。检测时，样品中的精斑（</span>PSA<span style=";font-family:宋体">）抗原与胶体金包被的抗体结合形成抗原抗体复合物，并沿着试纸流向</span>NC<span style=";font-family:宋体">膜的另一端。当该复合物流到膜上的</span>T<span style=";font-family:宋体">区时，固定在膜上的特异性抗体捕获该复合物并逐渐凝集成一条可见的</span>T<span style=";font-family:宋体">线，未结合的胶体金抗体流过</span>T<span style=";font-family:宋体">区被</span>C<span style=";font-family:宋体">区的二抗捕获并形成可见的</span>C<span style=";font-family:宋体">线。</span>C<span style=";font-family:宋体">线出现则表明免疫层析发生，即试纸有效；</span>T<span
