Application of Flow Cytometric Bead Array Combined with Rolling Circle Amplification on the Multiplexed Detection of Tumor Markers [PDF]
, 2012 肿瘤标志物的有效检测对于恶性肿瘤的早期诊断、治疗观察和复发预测起着至关重要的作用。在临床应用中，单组分检测存在特异性不强、阳性率低等不足。因此，迫切需要发展多种标志物的联合检测技术以提高肿瘤诊断的准确性。流式微珠阵列技术(flowcytometricbeadarray，FCBA)又称液相芯片技术，是将溶液中的待检测物质通过生物分子间的特异性亲和反应结合在微米级的经光学编码的微珠上，利用流式细胞术对同一份微量样品中的多种待测组分同时进行快速、定性、定量分析的新型检测技术。目前 ...
