Figure 2From: Inert coupling of IRDye800CW to monoclonal antibodies for clinical optical imaging of tumor targets HPLC chromatogram of 89 Zr-cetuximab-IRDye800CW (3.5 eq). The upper two channels show the UV absorption of cetuximab at 280 nm and IRDye800CW at 780 nm at a retention time of 26 min. The lower channel represents the radioactive signal of the coupled 89Zr.Back to article page
