Figure 1 From: Receptor oligomerization and beyond: a case study in bone morphogenetic proteins Experimental layout. Model of biosensor experiments with ligands as analyte passed over immobilized receptor ectodomains (ECDs) (a), receptor ECDs passed over immobilized ligands (b) and ternary complexes formed by perfusing an immobilized type I receptor with the ligand plus the ECD of a type II receptor (c).Back to article page
