Receptor-mediated endocytosis is an endocytotic mechanism in which specific molecules are ingested into the cell through a highly selective receptor-ligand interaction. Receptors on the plasma membrane of the target tissue will specifically bind to ligands on the outside of the cell. Cayman offers a diverse collection of assay kits with fluorescently labeled targets to monitor key receptor-driven events. With multiple fluorescent labels available, these kits have the flexibility to fit your model system.
