CY7-Dextran (MW 4000)

CY7-Dextran (MW 4000) is a near-infrared fluorescent tracer (Ex=740 nm, Em=770 nm) used to delineate cellular morphology and assess volume in vitro. Its application extends to vascular permeability and cell trafficking studies in vivo, leveraging the dextran backbone for enhanced biocompatibility and retention.
