The capture and detection of cells expressing a breast-cancer related membrane protein, namely a BT474 cell line expressing HER2, is demonstrated using ion-sensitive field effect transistors (ISFETs). BT474 cells were exposed to anti-HER2 antibodies and urease-conjugated secondary antibodies to induce chemical signal amplification by adding urea.
使用离子敏感场效应晶体管(ISFET),可以捕获并检测表达乳腺癌相关膜蛋白的细胞,例如表达 HER2 的 BT474 细胞系。BT474 细胞暴露于抗 HER2 抗体和脲酶结合的二级抗体,通过添加尿素来诱导化学信号放大。
