Ic50 binding affinity
WebbAlthough the results of this analysis are regularly referred to as affinity (e.g. Ki or K1 and K2), the model being used actually provides estimates for log IC50 which can then be converted to affinity values using a relationship described by Cheng and Prusoff (1973).

Webbtwo miniproteins previously described to bind to the S protein receptor binding domain (RBD) with high affinity. The multivalent nanostructures compete with the RBD−ACE2r interaction and neutralize SARS-CoV-2 virus-like particles (SC2-VLPs) with IC50 values in the pM range, preventing SC2-VLPs fusion with the membrane of ACE2r-expressing cells. Webb22 juli 2024 · Answer. Dissociation constant (Kd) is a type of equilibrium constant that measures the dissociation of a larger object into smaller components. It is the reverse of the association constant, being used to describe the binding affinity between the dissociated components. The inhibitory constant (Ki), on the other hand, is a term used …
