Dimerisk opløselige receptorer som for eksempel etanercept har en højere affinitet for TNF end monomeriske receptorer og er betydeligt mere potent kompetitive inhibitorer af TNF- binding til cellereceptorerne.
Dimeric soluble receptors such as etanercept possess a higher affinity for TNF than monomeric receptors and are considerably more potent competitive inhibitors of TNF binding to its cellular receptors.
