Figure 2From: In vivo breast cancer characterization imaging using two monoclonal antibodies activatably labeled with near infrared fluorophoresFlow cytometry studies. Flow cytometry studies showed specific binding of Pan-Alexa680(ON or SQ) and Tra-ICG to EGFR and HER2, respectively. Pan-Alexa680(SQ) showed brighter signals and increased fluorescent signals over time compared with Pan-Alexa680(ON).Back to article page
