Importantly, the strong NIRF intensity of DBCO-Cy5.5 (red color) was co-localized with Cas-3 antibody (green color) in the right tumor tissue (RT), whereas z-DEVD-FMK-treated LT showed the minimum intensities both of DBCO-Cy5.5 and Cas-3 antibody (Fig. 5d and Figure S11). The gene discussed is EFS; the disease is neoplasm.
