Slot: pKi
Description: Negative base 10 logarithm of the equilibrium binding affinity for a ligand that reduces the activity of its binding partner. Ki represents the concentration at which the inhibitor ligand occupies 50% of the receptor sites when no competing ligand is present

| ProteinLigandAssayResult | The type of study result describing the strength of interaction affinity - or enzymatic interaction - between a ligand and a target protein. Measured binding or enzymatic assay values are generally stated as the negative base 10 logarithm of the raw measurements. For instance (i.e., in a molecular interaction database like BindingDb) if a ligand inhibits a target protein with a pIC50 of 8.6, then the affinity parameter is pIC50 and the affinity value is 8.6. | no |
