| Abstract: | A Zn(II) complex (Zn(II)-Ida) was designed as the new fluorescent probe for His-tag fused proteins. Thanks to the tight binding ability to histidine-rich sequences and bright fluorescence property of the Cy5-appended Zn(II)-Ida probes, selective and clear fluorescent imaging of the His-tag fused G-protein coupled receptors on live cell surfaces was carried out. |
