摘要
目的 建立一种敏感的检测组织型纤溶酶原激活物 ( t- PA)及其抑制剂 ( PAI- 1)基因表达的方法。 方法 用异硫氰酸胍一步法提取细胞总 RNA,用单管 RT- PCR法逆转录 -扩增 t- PA、PAI- 1和内参照三磷酸甘油醛脱氢酶 ( GAPDH) m RNA,扩增产物经电泳分离后 ,用凝胶图像分析仪照相和扫描分析 ,测定各条带分子量和光密度值。 结果  PCR产物均与预期长度相吻合 ,且PCR产物量与扩增初始模板量之间存在良好的量 -效关系。 结论 本实验建立的单管 RT- PCR半定量法是检测 t- PA、PAI- 1m RNA表达的有效手段 ,具有灵敏、快速、简便、可靠等优点。
