Definition

A fluorescence imaging and contrast agent composed of an epidermal growth factor receptor (EGFR)-targeting affibody tracer molecule and labeled, through maleimide, with a near-infrared (NIR) fluorescent probe, IRDye 800CW, with potential use in the imaging of EGFR-overexpressing cells. Upon administration, ABY-029 targets and binds to EGFR-overexpressing tumor cells. Upon fluorescent imaging, the fluorescent dye can be visualized and EGFR-positive tumor cells can be detected.
