Liquid phase chip detection kit for early diagnosis of colorectal cancer

The invention discloses a liquid phase chip detection kit for early diagnosis of colorectal cancer. The liquid phase chip detection kit comprises an Fn antigen coated with biotin, a CEA detection antibody, a CA19-9 detection antibody, a microsphere coated with a goat anti-human IgA antibody, a microsphere coated with a CEA capture antibody and a microsphere coated with a CA19-9 capture antibody. The liquid-phase chip detection kit disclosed by the invention can detect different biomarkers in the same sample at a time by carrying out joint detection on various protein markers related to colorectal cancer, has the advantages of high specificity, high sensitivity, high flux and the like, and is beneficial to early recognition of colorectal cancer clinically. 本发明公开了一种用于结直肠癌早期诊断的液相芯片检测试剂盒，所述液相芯片检测试剂盒包括包被了生物素的Fn抗原、CEA检测抗体、CA19-9检测抗体与包被了山羊抗人IgA抗体的微球、包被了CEA捕获抗体的微球和包被了CA19-9捕获抗体的微球。本发明的液相芯片检测试剂盒，通过对结直肠癌相关的多种蛋白标志物进行联合检测，能够单次检测同一样本中不同生物标志物，其具有高特异性、高敏感性、高通量等优点，有助于临床对结直肠癌的早期识别。
