FAP Ligand 1

FAP Ligand 1 (FL) is a high-affinity small-molecule agent targeting Fibroblast Activation Protein (FAP) . It serves as a versatile tool for delivering conjugated payloads to FAP-expressing stromal fibroblasts and enables tumor imaging. This probe is utilized in preclinical oncology and fibrosis research for both in vitro binding assays and in vivo therapeutic or diagnostic applications.
