Monomeric and dimeric forms of soluble receptors can differ in their neutralization potential.
Recombinant soluble forms of transmembrane receptors can be produced in monomeric and dimeric versions. Binding affinity and neutralization potential of these different forms of soluble receptors depend on the quaternary structure of their ligands. Monomeric ligands will be bound with equal affinity by both forms, whereas trimeric ligands, e.g. members of the tumor necrosis factor family of ligands, interact with much higher affinity with dimeric soluble receptors than with monomeric ones.
