FAM-sgc8c aptamer (sodium) is a 5-FAM labeled sgc8c aptamer (sodium), which specifically targets human protein tyrosine kinase PTK-7, predominantly expressed on cervical cancer Hela cells. The binding of sgc8c aptamer sodium to PTK-7 induces the assembly of nanolabels on the cell surface, resulting in strong fluorescence and SERS signals with specificity for cervical cancer cells.
